possibly your blower motor reistat located in the hvac box and typically has four or five wires going to it. It is just a hard plastic like plate with wires in the middle and two screws holding it on. Check under the hood on the passengerside first.

The port is located in the supply rail that sits on the top of the fuel injectors on the top of the engine.

Need to have the codes read. You could have lost a ground wire. But this wouldn't cause a brake not to work.

This could be a few things that could cause this problem...Do you always hear the blower motor run with or without heat..?..knowing this would help me answer your question...It could be the heat blend door inside Your HVAC system behind dash ..These doors can stick or break..The best thing you can do other than trying to troubleshoot everything ,guessing and getting a headache is take it to a dealer and let them scan the system...They can find the problem with or without a trouble code...It may cost $ 100,00 dollars to have it scanned however it will save you money in the long run...

Diagnostic Test Code (DTC) C0265 is a POWER circuit code for the EBCM/Pump Motor Relay, not a ground code. This DTC sets when the voltage (B+) is too low at the EBCM when the solenoids and pump motor are commanded OFF. The voltage is supposed to be pulled low when the circuit is commanded ON. A ground problem with the EBCM is most likely to cause a failure of the EBCM to communicate with a scan tool. However, it doesn't hurt anything to check the ground. The main ground for the EBCM (G106) is located on the left rear of the engine near the knock sensor.

You may just need to have the code cleared. If you have a reader that will erase or reset dtc codes thats all it will take. some codes will reset just by doing a few drive cycles but other codes need to be cleared. There are a lot of places that will read or reset the codes for free if you don;t have a reader. That would also give you a chance to see if there are other problems such as brake pad sensors that are also part of the problem.

You need to get you alternator tested, it sounds like the current output is too low.

Dextron III, or if you can Dextron VI (full synthetic)

I'm facing the same problem. I am part way finished replacing the motor. Here's what I know so far. Disconnect wiring for blower motor (located up against the firewall on the passenger side). Unbolt the front face from the fan housing (5 7mm bolts). Here's where I get stuck - remove the squirrel cage from the motor, there is some kind of a clip holding the cage onto the motor - how does it come off? Once it is off, replace the old motor with a new one and put things back together.

Like most GMC Vans, remove the dashboard, then the heat core cover....

Installation is the reverse of the removal procedure.

If it has been in a flood, change it. Water will eat the valve body and pump gaskets. Even if it has been changed once, you won't get it all. Changing it a second time is a good idea. Use Dexron VI

Top center behind the top pulley. Follow the upper radiator hose to where it connects to the engine. I've always called that piece that the hose connects to, the gooseneck. So you take the hose off, then you take the gooseneck off and there sits the thermostat. Make sure you scrape off the old gasket and replace it with a new one. Also, don't try to run your van without a thermostat, your gas mileage will drop off the charts. We used to do that back in the day before all the computer controlled stuff when I lived in Florida. If I've helpped you, please remember to rate me. Thanks.

Common symptoms for failure:
  • Check Engine light is on.
  • Car is getting poor gas mileage.
  • Emission test fails.
  • The O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust as the exhaust exits the engine.
  • Starting with a few vehicles in 1994 and 1995, and all 1996 and newer vehicles, the number of oxygen sensors per engine has doubled. A second oxygen sensor is now used downstream of the catalytic converter to monitor converter operating efficiency. On V6 or V8 engines with dual exhausts, this means up to four O2 sensors (one for each cylinder bank and one after each converter) may be used.
  • http://www.aa1car.com/library/o2sensor.htm
  • This site gives generic info, with a list of: Most O2 sensor problems will cause the OBD II system to set one or more diagnostic trouble codes (DTCs) and turn on the Check Engine light. These are the OBD codes associated with O2 sensor faults: 39 listed You need to test and get the code that in turn tells which sensor.
  • The code displayed on your scan tool will indicate the type of fault, and identify one of the oxygen sensors by its position in the exhaust system.
    The oxygen sensor's location will be identified by position (sensor 1, sensor 2 or sensor 3), and by cylinder bank (bank 1 or bank 2).
    Most late model engines have multiple oxygen sensors, so which one is sensor 1, 2 or 3, and how do you know which cylinder bank is 1 or 2?
    On straight four and six cylinder engines, there is only one bank of cylinders. So all of the oxygen sensors will be bank 1. The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 sensor located in or behind the catalytic converter will be Sensor 2.
    On V6 and V8 engines, Sensor 1 will always be on the SAME side as the Number ONE cylinder in the engine's firing order. On GM and Chrysler V6 and V8 engines, cylinder number one is typically the LEFT front cylinder on the driver's side in a rear-wheel drive car or truck.
    On a GM front-wheel drive car or minivan with a transverse (sideways) mounted engine, the number one cylinder is on the front side of the engine (closest to the radiator) on the right (passenger side) of the engine.
