My AWD Light stays on in my 2002 Rendesvous. Internet suggested that electrical harness into front wheels may have parted due to being too short when installed. Had 2 dealers check this. No solution.
3rd dealer stated that the problem was in the differential pump valve, when the temperture sensor was giving a false reading and disconnecting the rear wheel drive. Replaced with GM Part 88896067, and it solved the problem. Mechanic stated that if it is ONLY the AWD light, then this is usually the problem. If the ABS Disable light also goes on, then it is the harness on the wheel sensor.

the versa trac awd is located under your vehicle.. it is not one part.. it is many parts that all work together to turn all 4 wheels..it starts at the front wheels and runs all the way back.
When the airbag light (SRS) is on or blinks it means a fault has occurred in the system and the airbag diagnostic monitor has disabled the system, the most common problem that turns the light on is a break in the connection to the steering wheel mounted airbag, this is due to a rotating ribbon contact that breaks under the steering wheel that connects the airbag to the wiring harness and the diagnostic monitor, the part is called the clock spring contact, a coiled up ribbon electrical contact that turns with the steering wheel while maintaining a mechanical connection to the airgag mounted on the steering wheel, to replace this part you must disarm the airbag system and remove the steering wheel, this requires a special steering wheel puller tool and that you disarm the airbag system before you start the work, to do this disconnect the battery negative cable for 15 minutes prior.
I had this happen to my car and paid entirely too much to the dealer to get it fixed. For me, it was the harness that you think it is, and it affected the battery- I needed to replace it- and also the computer. I'm not sure if mine was frayed, but I've heard that this harness has been known to become frayed and shorts out because of that, which is what I imagine causes the failure, and the shorting out is what destroyed my battery and fried my computer.

1st when the airbag light is on the system is disabled, so if u have an accident they will not work, as to the common cause read below.

i got a 98 bravada and my AWD light was on, what i did to fix it was replace the transfer case motor and thats all, i did a bunch of research and found out that the transfer case motor is the main conponent with of your AWD it tells the transfer case when to give the front wheels power. try replacing that
No, it is probably not related. Usually the ABS and traction control light is either a wheel sensor problem, located in one of the wheel bearings, or most likely in the wire harness from the wheel bearing sensor. Remove wires and spray clean with a good solvent electric spray, and check the condition of the receptacle. I have had these problems with my 02 AWD so many times it has become almost routine. GM really have a problem with this type of speed sensor in the wheel bearings. In the AWD model, it keeps the car in FWD if the ABS light is on for any reason. JUNK!
I own the 2002 Buick Rendezvous CX and I've encountered the same problems listed here. The ABS / Traction Control Lamp stays on and was throwing a code for the left wheel speed sensor as well as an anti-lock brake code (both in the wheel bearing hub assembly). I replaced the left and right front wheel hub assembly yet this did not eliminate the abs codes.
Ultimately, I traced this problem to a break in the wire that leads to the left hub assembly. Although the sensor was properly connected, the wire (which is encased in a plastic housing) was broken. This is the wiring which leads from the abs wiring harness under the hood down to the left wheel abs sensor.
I would suggest that you simply remove the left wheel and inspect the wire that leads to the abs sensor (there is only one wire on each wheel). Mine literally fell apart when I removed the plastic housing around the wire. I spliced the wire together and put it back in the plastic housing. After this, my abs codes disappeared and my anti-lock brakes began working again!
This is a simple fix that many people spend $1000 + on by replacing the hub assembly which does not fix the problem.
Our 2002 did the same thing. Easy cheap fix! Pull the wheel off and check the wiring that goes to the wheel sensor. You will find after removing a few inches of wrap, a broken wire or two. This could be on either wheel, so check both. Fix the wires back up and you are good to go. Hope this helps!
