Not sure. I know that it needs a speed signal, or it will not run (the compressor doesn't run while you are driving). You are right, the logic controls are buried in the compressor. But the LED will light even if the compressor does not run, according to the wiring guide (assuming that the...

I am not great at the wiring schematics, but could the problem be the ground Get in the back and watch the led on the manual inflator switch. Have someone start the vehicle. The number of flashes on the LED (1,2, or 3) is an error code that helps you diagnose the electronic suspension. Even...

Sorry, I did actually have the wiring diagram.

Try this. Apparently the Compressor will flash - that is the diagnostic code - if something is wrong. You will need someone to start the vehicle for you. Check out the pics.

When you start your vehicle, the compressor should kick in no matter what the level sensors say (at least in my experience), even if the air springs are fully inflated. If this is not happening, it has to be a wiring or fuse/relay issue. Sorry, I don't have a wiring diagram for the air...

Sorry for your problems. I also have a 2011 Traverse. Great driving vehicle, love the ride, handling and solid suspension. But it seems like I am always repairing something. Seriously. I too replaced the alternator (tough job, used a salvage one because I did not want to risk aftermarket)...

I realized that I didn't follow up on this old thread. So this summer I finally dug back into the rear A/C. Previously, I had a bad actuator in the back, but when I tested the A/C at the back it did not blow cold. Of course, I was at idle. Never even thought. This summer, my son was sitting...

It took me a long time to get to this job. I wanted to see the pressure on Torque because occaisionally the pressure gauge would drop to zero for a few seconds (along with a warning on the DIC) and then swing back to max. I decided to replace the pressure sensor in the back of the engine. Not...

Thanks for the detailed information. I will check that out and post back.

I was assuming the stepper motor was bad - but perhaps it is the wiring. My profile doesn't say 2003? The PID says [GM] Oil Pressure (Engine) 221470 in the PID Editor.

My oil pressure gauge on my Envoy has never worked since I owned it. The needle is maxed to the right, even if I just turn the key to "on" and don't start it. Is there a way to read the oil pressure with Torque Pro? It doesn't seem to display for me. Or would the reading even be close to the...

A good resource for this is crutchfield.com. This website will show you the correct speakers for your system (and sell you some, if you want). But the rear speakers are not special, even with the Bose system. I think they are 6 1/2 in the back. I did replace mine, it was not difficult, just...

No need to grease the splines. If you want you could put on a little anti-seize, but I have never had a problem freeing the splines from a hub that I am replacing. Freeing the hub from the backing plate, that is a whole different situation. Almost every one I have done has been extremely...

The wire harness is on that side under the plastic panel. It only makes sense.

The trailer brakes will still work as long as the connector is linked and the brake controller is powered, the dead trailer battery has no effect on the trailer brakes as long as you are connected. Mooseman is correct about what will happen if the trailer separates. Also, if you had no trailer...
