Thanks for the suggestions. I have just emailed GM to see if they can provide me any assistance. Later today I will speak with the service advisor further to see if he can provide me with specifics as to what they have found thus far. Right now I leaning toward having the leakdown test performed as this seems to be the usual diagnostic test for serious engine problems.

Hmmm....I wonder if you have a loose wrist pin. There is a test for that---you run the car at idle, listen to the noise, then pull or short out one spark plug, and if the noise doubles in frequency, it was a wrist pin.
 
There's also "piston slap", or a collapsing piston, but that's less likely.

#2499 of 2506 2004 Rendezvous = heated driver seat not working by shorteeeee74

Feb 02, 2013 (4:43 pm)

I have had the car for over 3 years, and while there are other issues (replaced sensor in front wheel hub, driver side window rolls up/down when it wants, new battery in keyless remote, but all four doors don't respond in locking or unlocking), but my new primary concern due to how cold it is......my driver's side seat no longer heats up. The light on the switch still lights up when you turn it on/off, but no heat. The owner's manual says fuse #42 works this function, but light would be out if it was a fuse. The wiring under seat looks hooked in properly...what do I need to be looking at here?? I'm so spoiled to this feature......I want it fixed fast and cheap!!!
Thanks alot

Hi!
This is not a simple problem unfortunately. Possible causes include:
- Either heating element in the seat open (seat cushion or back)
- The heating-control module on the seat frame under the seat cushion
- The PTC circuit breaker in the wiring harness under the seat
- The power wiring to the seat
- The ground wiring to the seat
- Poor connection in the connector under the seat or elsewhere in the circuit
 
If you have someone familiar with electrical trouble-shooting, I can send you the wiring diagram for this function and a GM trouble-shooting chart.
 
I read that about 90% of the time, this problem is caused by the heating elements in the seat itself. To replace those requires hog-ring pliers and some familiarity with removing and installing upholstery because you have to disassemble the whole seat to get to them.
 
One shotgun possibility would be to check with your local wrecking yards to see if they have a fairly low-mileage Rendezvous to get the seat out of. Make sure that if your RDV has memory seats, the donor car does too....... and vice-versa. If your problem IS in the seat, this should take car of it, assuming the heating function is good in the replacement seat (try to check it at the yard before it's removed from the vehicle)
 
To remove the seat, use the adjusting button to move it all the way forward, then remove the two large nuts under the back of the seat. Then run the seat all the way back and remove the two large nuts under the front of the seat. Then you can tilt the whole seat back and disconnect all the electrical connectors underneath and carefully lift the seat out. Reverse the directions to install the new seat.
 
Hope this helps! Let me know if you want the other info Nick

Have 2002 Buick Rendezvous. Is there any way to unhook the AWD disable light without hurting anything else?

I don't know of anyway to make the light magically go away, but I think it might be just as easy to correct the problem (unless something has been done to make AWD not work). Fairly common suspect for the light to come on is the C-305 connector under vehicle just behind drivers seat. If there is an issue with it other problems may occur (starting/stalling/ fuel gauge issues)

You might want to do a google search on 'gm c305 connector' . Should be able to find how to correct the problem

I am not too sure about t he "305" connector. I say this, only due to the fact that, that is just that, a connector, to get the info to the BCM. I can say, if you do know that this "IS" the issue, i would check the rear wheel sensors. only because i have had the front wheel sensor connector break apart (long story, wife driving), Anyway, After fixing that is issue with the broken connector there, my AWD light issue, went away. IF you know for fact it is that 305 , i would check the other ones down the path, to those sensors, maybe it could be a wheel sensor, which is not all that big of an isssue to fix....
hope this can shed some light.

Buick Rendezvous BCM in in the center console, you must remove most of the center console to get at the BCM.
