our temperature control actuator is bad. It's a little motor that moves the temp door. They are about $70 at the dealer. To change it you need to remove the knee trim panel on the passenger side (3 screws, 7mm socket). The actuator is in the center above the transmission hump. It has one harness plugged into it and 2 screws (5.5 mm). Take the screws out and it should drop straight down. Align the actuator with the lever on the door and put the screws in. Plug the harness back in. Turn your temp control to cold and remove the HVAC 1 fuse. Should be in the fuse panel on the drivers side of the dash. Turn your key to run and leave it on for at least 1 minute. Turn your key back off and put the fuse back in.
P.S. The trim panel is a PITA to get off, so while you have it off check to see if you have the cabin air filters and change them while you are under there.

Also there is an article in the Tech Corner on changing the cabin air filters.

Does the vehicle start an run ? If it does ,the brain as you call it is working fine . The check engine light has nothing to do with the PCM /ECM sensing problems .You probably should take your vehicle to a qualified repair shop .

Yes we can ! With the light on and or flashing , DTC'S - diagnostic trouble codes are stored in the 4X4 control module . Have the codes check , not at auto zone or any other parts stores . There code reader tool will not pull this codes . Need to take to a qualified repair shop . Testing also needs to done , not guessing an throwing parts at it . This 4X4 system can set a number of codes .

DTC C0387 Unable to Perform Shift
Circuit Description
The transfer case encoder is a switch that converts a shaft position, representing a mode or range position, into electrical signals for use by the transfer case shift control module. The encoder houses 4 Hall effect sensors that are used for channels P, A, B, and C. These sensors provide a path to ground, when a magnet, (part of the Motor Encoder), passes over them.
The transfer case shift control module supplies an 8 V reference and a ground circuit for the encoder hall effect sensors to function.
The transfer case shift control module supplies current limited 5 V on all the channels, thus as these channels are pulled to ground, the module can interpret the location of the transfer case shift position.
This DTC detects that the transfer case is unable to successfully complete a shift to a requested mode or range.

Can you get in the vehicle though another door and use the inside
handle to open the drivers door?

2000 Chevrolet... | Answered on Apr 27, 2017


Bleeder screws , If you haven't replaced the unit you don't need to do anything with them . Don't need to have the vehicle running , just bleed the brakes normally . If you have replaced the Electro-Hydraulic Control Unit you need a factory scan tool to cycle the unit solenoids
Important:
• Use the two-person bleed procedure under the following conditions:
- Installing a new Electro-Hydraulic Control Unit (EHCU) or new Brake Pressure Modulator Valve (BPMV).
- Air is trapped in the valve body
• Do not drive the vehicle until the brake pedal feels firm.
• Do not reuse brake fluid that is used during bleeding.
• Use the vacuum, the pressure and the gravity bleeding procedures only for base brake bleeding.
Raise the vehicle in order to access the system bleed screws.
Bleed the system at the right rear wheel first.
Install a clear hose on the bleed screw.
Immerse the opposite end of the hose into a container partially filled with clean DOT 3 brake fluid.
Open the bleed screw 1/2 to one full turn.
Slowly depress the brake pedal. While the pedal is depressed to its full extent, tighten the bleed screw.
Release the brake pedal and wait 10-15 seconds for the master cylinder pistons to return to the home position.
Repeat the previous steps for the remaining wheels. The brake fluid which is present at each bleed screw should be clean and free of air.
This procedure may use more than a pint of fluid per wheel. Check the master cylinder fluid level every four to six strokes of the brake pedal in order to avoid running the system dry.
Press the brake pedal firmly and run the Scan Tool Automated Bleed Procedure. Release the brake pedal between each test.
Bleed all four wheels again using Steps 3-9. This will remove the remaining air from the brake system.
Evaluate the feel of the brake pedal before attempting to drive the vehicle.
Bleed the system as many times as necessary in order to obtain the appropriate feel of the pedal.

there are like 3 for a 2000 chevy silverado. 1 on left side of dash accessible only when door is open. 2 on right side of dash, not sure those fuses are applicable to you tho, and 3 under hood beneath a plastic cover that you snap off by pulling on.

Lets examine your readings first.
Code 154 means the sensor is not switching from lean to rich enough in 60 seconds. And there is no such thing as average voltage.
The O2 sensors generate their own voltage by measuring oxygen in the exhaust. They also have heaters that get power from a relay.
But a problem with the heaters should be a different code.
When the engine is running, the computer varies "on" time for the injectors based on engine temp, throttle position, and unburned fuel in the exhaust. So when the O2 sensors send voltage higher than .5 to the computer, the computer calls that RICH and shortens on time for the injectors. Then when the O2 sensor drops voltage down below .5 it reads LEAN, and the computer lengthens on time for the injectors.
This back and forth switching should happen several times each minute. Like the tick tock of a clock.
If the sensor(s) are slow to switch, or they stay on lean or rich for more than 30 seconds, you get the code 154. Each sensor has a different code for the same issue.
It could be a sensor problem, or a fuel problem, or something else.
Too lean can be low fuel pressure, too rich can be not enough air flow coming into the intake.

If there is no oil pressure or the alternator is not working, the fuel pump won't either. Check the oil pressure sender and the alternator for a problem there.

Both the hinge bolts and the latch bolts can be slackened off and the door position changed. It's a matter of determining where you want to have it, where it is now, and around what point it has to move to get the desired result.
Sometimes it helps to support the weight of the door on a small floor jack. Use a block of wood to prevent damage to the door.

You may want to replace the caliper as it is very hard to rebuild them and get the honing correct so the piston doesn't stick.

I think around 1993 and some 1994 had r12 but if you look on top of the dryer, if it is the original it will tell you what type to use to recharge the system. or on the radiator support in the front there is a sticker with the type on it.

2000 Chevrolet... | Answered on Nov 29, 2015


The recharge valves you buy at the parts store will only go on the low side of he system, which is normally the line that goes to the dryer.
