does anyone know where to find the coolant fan temp sensor on a 2003 chevy venture.
Thanks for any help you can give me.
located in thermostat housing or in intake nearby (where top hose connects from radiator to engine)

Van has been overheating for about the past 2 weeks. When I accelerate hard, the temp gauge drops. Two days ago, the temp gauge reached it's limit and the engine shut itself off. In the last 4 or 5 days, the van does not make it more than a few miles down the road before the temp gauge shoots up. I have checked the coolant tank, and it is full, but the fluid appears to be extremely dirty to me. Could this have caused a clog? I have noticed that both fans are coming on, and remain on after the engine shuts off for a few minutes. Also, when I turn the heater on to try to help with the overheating, it blows very cold air, and causes the temp gauge to rise faster. I know that there is a leak in the oil lines somewhere. Could that also be the culprit?
Almost sounds like the same symptons as my van. Turns out the guage was not the problem. The van was in fact running hot because the electric radiator fans were not kicking in when the engine was hot. I replaced the relay switches for the fans. There are two of these in the fuse panel under the hood. There has been no problem with overheating since

location of engine coolant temperature sensor on chevy venture 98
It is a 2 wire seneor under the throttle body. You will have to remove the air breather and it will be a brass/black plastic sensor. A 3/4 socket will fit it.Good Luck

Hello? I'm installing a new CD player on my cousins 97 Chevy Venture, except there is one problem. The factory installed stereo dosen't have a wiring diagram with it. I can't tell which wires to connect to make to speakers work and I don't want to damage her new stereo by trying test the wires either. I tried all night to find a wiring diagram but the only closest thing I came to was a 97 Chevy Astro van and I'm assuming that they may have the same stereo system and so they Astro diagram might work? Can you tell me if the factory wiring diagram for the Astro would work? If that is not possible then can you show me where I can find a free one for the 97 Venture because to download? I don't use credit cards on the internet so if you could point me in the right direction I would appreciate it. Thank you for your time.
your installing an aftermarket cd player in place of factory radio?
it would be best to buy the harness adapters. they plug into the factory harness and will tell you what all the wires are. harness is usually only 10-15 dollars. here is the diagram also.

I own a 2004 Chevy Malibu that I just recently took into a body shop to have the hood and valve cover to my engine replaced. After leaving the shop I noticed that my windshield wipers that were in perfect working order the day I dropped it off suddenly only work on the highest setting and when turned off do not park in the proper setting. I called the shop and they told me that there is no way that they could have had anything to do with that with the work that they had done. Can anyone out there help me?
It is the Wiper Motor causing the Problem and will need to be Replaced. They could have caused it by Bumping the Wiper Motor Casing when replacing the Hood or when Working on the Motor. Please Rate my Response, I need all the HelpI can get! Thanks!

My mechanic told me my P0107 is possibly bad. Is this located in the same location as the P0108
P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
The Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold pressure (vacuum). 5 Volts is supplied to the sensor from the PCM (powertrain control module). Inside the MAP sensor is a resistor that moves in relation to manifold pressure. The resistor varies the voltage between about 1 volt to 4.5 volts (depending on engine load) and that voltage signal is returned to the PCM to indicate manifold pressure (vacuum). This signal is essential for the PCM to determine fuel delivery. A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low.
Potential Symptoms: Anytime the MAP sensor signal is low the vehicle will likely have a very difficult time starting. Other symptoms may include:
* Hard to start
* Long cranking times
* Sputtering/missing
* Blowing black smoke
* Poor fuel economy
* Dies intermittently
* MIL(Malfunction Indicator Lamp) illumination
Causes: The causes of a low MAP sensor signal circuit (P0107) could be any of the following:
* Bad MAP sensor
* Open or short in the signal circuit
* Open or short in the 5 Volt reference circuit
* Ground circuit open or shorted
* Bad PCM
Possible Solutions: First, using a scan tool with the Key on and engine running, monitor the MAP sensor voltage. If it is reading less than .5 volts, turn engine off, unplug the MAP sensor and, using a DVOM (Digital Volt/Ohm Meter) check for 5Volts on the 5 Volt reference circuit.
1. If there is not 5 Volts on the reference circuit, then check for the reference voltage at the PCM connector. If it is present at the PCM connector but not the MAP connector, repair the open in the reference circuit between the PCM and MAP harness connector. If 5 Volt reference is NOT present at the PCM connector, check powers and grounds of PCM and repair/replace as needed. (NOTE: On Chrysler products, a shorted Crank sensor, Vehicle speed sensor or any other sensor that utilizes the 5 Volt reference from the PCM can short out the 5 Volt reference. To fix simply unplug each sensor one at a time until the 5 Volt reference reappears. The last sensor unplugged is the shorted sensor.)
2. If you have a 5 Volt reference at the MAP connector, jumper the 5 volt reference circuit to the signal circuit. Now check the MAP voltage on the scan tool. It should be 4.5 to 5 Volts. If it is, replace MAP sensor. If not, repair open/short in the signal circuit wiring and re-check.
3. If all appears okay, perform a wiggle test. Start engine and manipulate the harness, connector and tap on the MAP sensor. Note any changes in voltage or engine speed. Repair connector, harness, or sensor as needed.
4. If the wiggle test checks out, use a vacuum pump (or just use your lungs) to draw a vacuum on the MAP sensor vacuum port. As you add vacuum the voltage should decrease. With no vacuum, the MAP sensor should read approximately 4.5 volts. If there is no change in MAP sensor reading on the scan tool, replace MAP sensor.
MAP Sensor DTC's: P0105, P0106, P0107, P0108 and P0109.
Hope helps (remember rated and comment this).

97 chevy venture mini van 3.4L 4 speed electronic transmission will not shift in to forth gear shifts from first to second to third no problem but will not shift to forth what can I do to fix this problem?
4th clutch hub splines are stripped off. GM didn't harden the splines until 2004 or so so the early model gradually wear to the point where they are so thin they strip off - and then, no 4th gear

Chevy Venture passenger side window won't roll up from the passenger side switch or the drivers side switch? I was able at one time to roll up from drivers side switch but that no longer works.
wiring harness on passenger door has a severed wire

can anyone tell me what may be wrong with my chevy venture van's wipers? They first started acting up by not wanting to rest and then they wont shut off. i did unplug the fuse, but it's only a quick fix...is it the switch or the wiper motor on the fritz?
The problem is in the wiper motor assembly. Did you ever notice that when you switch the wipers off they always go back to the home position? This is due to a switch that keeps the wiper motor operating until the wipers are parked. In many older GM vehicles this is accomplished with a leaf type switch which opens when the wipers are in the correct position. when the dash switch is turned on this switched is bypassed keeping them on-when the wipers are turned off the motor continues to operate until this connection is broken.
Inside the wiper motor housing there is a nylon gear that drives a cam that cycles the leaf switch-most likely the gear has become damaged so it no longer drives the leaf switch allowing the switch to remain closed. A cheap fix is to disassemble the motor unit and piece of tape between the contacts. Although the wiper will not park properly they once again can be controlled by the dashboard switch.
In later vehicles the wiper position is located with an electronic sensor with a small PB board - the repair of this gizmo is beyond the scope of most shade tree mecahnics - so the solution is to replace the entire wiper motor assembly - unfortuneatly.

the code take's a while to set , then i reset it and it takes about a week of driving for it to reset , is there a blockage problem with the EGR and is there a passage that leads to the egr on the throttle body ,, should i clean all i find ? no drivablity problems when i the light is on ,,108,000 mile runs super nice even when code is set
i would definitely clean out any residue i find in the exhaust passaged-cloggage can cause definite problems-clean all you find and go from there,if that doesnt work and code come back-replace the egr valve
