I have a 2001 Chevy Silverado and my wipers only work on high. What would cause this to be happening? I really need to get this fixed as soon as possible.

The fault in this circuit board is quite common and is attributed to bad
solder joints from either design error or manufacturing flaw. Symptoms
which indicate a bad circuit board include (but are not limited to): wipers
will not work or work intermittently; wipers stop working for no apparent
reason, maybe even in mid-stroke; wiper function is erratic, with no delay
feature, delay is the same regardless of setting, or no low- or high-speed
setting; wipers may start to work if you tap on the wiper module or move the
You have a choice of either Repairing your existing circuit board yourself,
or Replacing it.
Replacement - You have at least three options available to you, depending on
your relationship with your dealer and how much of a stink you want to put
1. Pay for the replacement part plus the labor to have the dealer install it
(~$50 for the part plus ? for labor. Most expensive, least work).
2. Pay for the replacement part and install it yourself (~$50 for the part,
your labor is free. Takes about 15 minutes.).
3. Have the part replaced under recall if applicable (Free, minus the time
your truck will be in the shop. Least expensive, most work.).
4. (Repair it yourself - Instructions below after Replacement)
Option #1 is very straightforward, just go down to your local dealer and
have him do the work and pay the bill when he is finished. You don't even
have to read any further.
Option #2 is also very straightforward. Have the parts department research
the correct part number for your model year circuit board, purchase the part
from them and install it. The wiper module is a small 2"x 4" black box
attatched somewhere near the top of the firewall on the driver's side. It
has the wiper motor mounted to it, and an electrical connector plugged into
the end. Remove the electrical connector first, and using a Torx (6-pointed
star) driver, remove the cover from the module. The circuit board sits
directly underneath the cover and will be coated with grease. Gently pry
the circuit board out of the module, do a little spring cleaning inside the
case and add a dab of grease to the drive gears if needed. Install the new
circuit board in the same manner as the old one was. Clean the inside of
the cover and reinstall with the same Torx head screws.
Option #3 gets a little involved. First you must find a recall notice for
your truck. Start by checking on the internet at http://www.nhtsa.gov and drill
down thru the links for recalls to determine if your truck is actually
listed (there are other sites to check as well). Just because your truck
may not be listed doesn't mean it's not under recall. It could easily
depend on how your truck is described. For example, a 1995 Chevrolet C1500
Pick-up could easily be listed as a C1500, 1500, 1500-3500, C-Series, C/K
Series, Chevrolet Truck, GM Truck, C10 (the old designation), etc. It would
pay to look under as many designations as you can think of before giving up.
If you find your truck as listed, so much the better. Print out a copy of
the recall and wave it at your dealer's service manager and they should fix
it No Questions Asked. If they still refuse, contact Chevrolet/GMC Customer
Assistance and/or the NHTSA's hotline (both are toll-free and listed on
their respective web sites).
If you do not find your truck specifically listed, all hope is not yet lost.
Search for the same truck under a different model year, or a substantially
similar vehicle which does have a recall (For example, the Chevy Blazer
shares the same wiper components as the Chevy S-10 and Astro, the GMC Jimmy,
Safari and Sonoma, the Olds Bravada, etc.). Print out a copy of the recall
for the other vehicle and go to your dealer's parts department. Have them
search for the part number of the circuit board for the recalled vehicle,
then for the part number for your truck. Odds are in your favor that they
will both be exactly the same. Hence, your wiper module is one of the
faulty ones being recalled and should be covered but your truck may have
been left off the recall list. Take this info to the service manager and
depending on how much he wants to keep you as a customer, he will find a way
to have the board replaced under the recall. If not, then you still have
options #1 and #2 above, or you could fix your existing board yourself.
Repair - You can easily repair your existing board if you know how to turn a
screwdriver and know which end of a soldering gun to hold. If you haven't
mastered either of these skills, then have someone else do the job for you.
Step 1 - Locate the wiper module and remove the circuit board as described
in Option #2 above. Be VERY careful removing the circuit board. Do not
crack, bend or break it or you're outta luck and will have to buy a new one.
The circuit board is approx. 2"x 4" and has two distinct sides. The top is
the side where all the components live, especially the large black socket
for the electrical connector (more on that later). The bottom is where all
the lead wires from the electrical components poke thru the board and are
soldered to the printed circuit. Carefully wipe the excess grease off the
Step 2 - The fault in the board is caused by bad solder joints holding the
large socket onto the printed circuit. If the board itself is cracked or
broken, then you will have to get a new one. Carefully inspect the tiny
mounds of solder underneath the large socket on the bottom of the board.
Each drop of solder connects a lead wire from the socket to the printed
circuit. A bad solder joint may look like it has a tiny circle in the drop
of solder around the wire end, a chip or crack in the little ***** of
solder, or it may be too small to see. At this point you will need a
soldering gun and solder, and a steady hand.
Step 3 - Set your circuit board bottom side up so you can see the solder
joints for the socket onto the printed circuit. Heat up your soldering gun
and apply just a tiny drop of solder to the tip. Place the hot tip with the
melted solder directly onto the existing solder joint in question just long
enough until the gun melts the existing solder and the new solder mixes in
with it. Remove the gun from the work and allow to cool. Remelting the
original solder and adding some extra should repair the joint and make
continuity again and reinforce it. Repeat for all the solder joints in
question, and/or all the solder joints for the socket. Don't overheat your
work, or solder may run down and create a short to another circuit, or you
may unknowingly fry a component on the other side of the board.
Step 4 - Allow everything to cool, then reinstall the board as listed in
Option #2 above.

I have a 2001 chevy silverado. I checked my fluid level and it is good.
I can put my truck in drive 3,2,1 and it will not go anywhere.
I put my truck into reverse and it will go just fine.
I am wondering what might be the issue is my transmission blown or do i have a sensor that could be bad?
fisrt gear clutch is burned out , if you push the truck with a car up to 30 mph and drop it into drive you will get 2nd and 3rd , but when you stop you have nothing. if first gear clutch burns up you don't get any forward gears.

I have a 2001 chevrolet silverado with the following codes C0265,CO241 C0245 C0246 CO251. ABS & BRAKE LIGHT COME ON AND OFF Thanks Joey
Posted by xcowboyup0... on
looks like you need an ebcm. You can check the ground under the drivers side door attached to the frame, make sure it is clean and tight.
DTC C0241-C0254 or C041-C054
Circuit DescriptionThe ABS relay supplies battery voltage to 6 valve solenoids. The electronic brake control module (EBCM) microprocessor applies the grounds needed to activate each solenoid. The low side of each solenoid coil has a feedback circuit to the EBCM microprocessor. When a solenoid is commanded OFF, the feedback voltage is high. When a solenoid is commanded ON, the feedback voltage is low.
Conditions for Running the DTC • The ignition is ON. • The vehicle speed is greater than 6 km/h (4 mph). Conditions for Setting the DTCThe EBCM detects an internal malfunction.
Action Taken When the DTC Sets C0241, C0242, C0245, C0246, C0251, C0252, C0253, C0254If equipped, the following actions occur:
• The EBCM disables the DRP/ABS. • The ABS indicator turns ON. • The red brake warning indicator turns ON. C0243, C0244, C0247, C0248If equipped, the following actions occur:
• The EBCM disables the ABS. • The ABS indicator turns ON. Conditions for Clearing the DTCThe conditions for setting the DTC are no longer present and you use the scan tool Clear DTCs function.
Diagnostic AidsAn intermittent open/shorted solenoid DTC can be set by several different internal EBCM problems. Replace the EBCM if an open/shorted solenoid DTC continues to set intermittently.
Did you perform the ABS Diagnostic System Check?
Go to Step 2
Go to Diagnostic System Check - ABS
Go to Step 3
Go to Diagnostic Aids
Important: Following EBCM replacement, use the scan tool to perform the Tire Size Calibration procedure and the Trim Level Calibration procedure, if applicable.
Replace the EBCM. Refer to Electronic Brake Control Module Replacement .
Did you complete the replacement?

What is the process to change the fuel pump on a 2001 chevy silverado 1500?
Posted by kajunrose1 on
take the six bed bolt loose and then take three buddies slide the bed back put in the new pump slide it back n place and put the bed bolts back in. if u drop the tank u can easily break the hard plastis lines that go to the fuel tank. u only have to take the fill lines and taillight wires loose this way its alot quicker, and easier.

new calipers new pads had rotors turned new brake lines also now free but when drive truck they stick
Posted by Guest on
I had the same problem and replaced both calipers with no change, I figured it was the master cylinder. When I pulled off the master cylinder I saw the vacume booster had about 2 cups of brake fluid in it which leaked from the front of the master cylinder. I replaced master cylinder and vacume booster and brakes work great now.

in 2001 chevy silverado when trying to turn ignition key the switch tend to lock i have to playu with steering wheel and play with key trying to turn it on rapidly after five of six attempts it will eventually turn and fire up the truck. is this due to a bad ignition switch that need to be replaced or something else.
Not the igniton switch, its the ingition cylinder and or the housing. The switch is not part of what you are really turning. It's connected to it via gears. The common problem is the key gets worn out and the tumblers wear also. Eventualy they do not line up right and will not make the "bar" drop in the cylinder to allow it to turn from the off positon. If you have the title in your name and the key has never been rekeyed or the code has been changed you can go down to a dealership with all of the info for the truck and they can cut you a key from the vin number. You can try that first before you put a cylinder and housing in it.

The cargo lamp on message stays on. The dome light doesn't work now either. Verified that the cargo lamp is not on and the the dome override button isn't deppressed. Any ideas?
Posted by david... on
Check under the hood, in the fusebox, for a fuse label ctsy (courtesy). It'll be over the driver side wheel. Replace it, if blows and, you have a wire touching bear metal somewhere. Good luck!

while driving in the snow the last few days I applied the brake pedal hard a few times to see how slick the road was and to see how the brakes would react, now the abs light came on and wont go out, light stays on all the time. what do you think the problem could be?
Posted by rick088 on
Once the ABS light is on there is a problem with the ABS system. You can't really guess with this stuff. Also it becomes a safety issue when abs light is on the ABS system is in-operable. Here is my advice take your vehicle to any AUTO-ZONE store and they will check for FREE and let you know why this light is on it could be anything form abs sensors(wheel sensors) or something like that, they are four of them one in each wheel so make sure to get exact info as to what is the exact code and meaning. Good Luck feel free to contact t me if ou need more info
