#1963 of 2541 Re: AWD Disable Indicate comes on [jpierce]
Feb 24, 2008 (8:47 am)
AWD Disable (with our without the antilock light) comes on for, from what I can tell from all the posts here and on the Aztek forums for 3 reasons:
1. Wheel Bearing/Speed Sensor failure.
2. Wiring harness failure.
3. AWD Control Valve Failure. (Thanks Dan Tucker, Pine Bluff, AR)
I was lucky enough to have BOTH 1 and 2 on my wife's 03 RDV. Left Rear bearing was SHOT - the speed sensor cover had rusted through. Put on the new bearing and when you applied the brakes, the anti-lock would kick in - even under light braking. I still had a problem.
So I went after electrical - it seemed logical, since the AWD Disable light would initially go off (the computer does a diagnostic every time the car is started, and apparently if it doesn't get a good signal from ALL wheel sensors - it sets the light)
Took the connector from the wheel bearing I had just replaced and soldered it to the end of a $1.00 extension cord (you need at least 9 ft). With the circuit energized, the power side of the plug should show a consistent carrier signal - mine was 4.75 volts to ground. You can also OHM them to the ABS computer connector - all connectors should ohm less than 10 (see where the extension cord comes in handy??)
After all 4 wheels run through ohms and volts - found the left front speed sensor power line broken off right at the connector. With some choice words and REALLY lucky connector work - wire reconnected and problem solved.
If you are unlucky enough to have the control valve - the part number is 88896067 and is $107 plus shipping from gmpartsdirect. You'll also be out about $75 for versatrak fluid. Pretty easy to change, I am told.
The car has 92,000 on it and the bearing was original. Don't know the age of the other 3 bearings, but I have a spare rear (from my Aurora) when it goes.
One other good thing from this - the rear end groaning with parking lot maneuvers seems to have gone away with the installation of the new bearing.
Next stop - air compressor and self leveling.

Has the dealer (or some other good mechanic) run it on their diagnostic machine? My Aurora had a similar problem - sporadic engine stalls - at just about any speed - the first time it happened was at 60 mph - pretty exciting.
When the dealer ran the diagnostics for my miss problem - they alterted me to a Crank Position Sensor issue. I changed them (2 on a Northstar) about a month ago and not one stall or hiccup from the engine since. The miss was cured with a new coil pack.
You might have the CKS and a Camshaft circuit problem.

Hi,,my stalling was only when I was slowing down (5-10mph) and making a turn such as going onto a parking lot or a turn. It was abrupt with no sputtering , no lights, just car off,,,,I would always call Onstar but they did not find a problem,,and dealer could not find problem at first,,,,,,they did on last visit say it was the fuse block (engne) and after some arm twisting and a receipt fron 2006,,,fixed it for FREE,,,,,,,finally running good,,,,,,,,for now

I received the same letter. My problem with the 04 Rendezvous is the Low Fuel light and fuel gauge problem as described in previous posts. According to dealer, fuel sensor inside fuel pump needs to be replaced at a cost of $650. In addition, service engine soon light is on all the time. Does anyone know what the actual repair is with regard to the recent letter and if I can coordinate the repair of my fuel sensor with that?
#1967 of 2541 Repair of fuel sensor
Feb 26, 2008 (5:08 am)
I had the same problem with the Low Fuel Light and Fuel Guage. When I took it to the Buick garage they said i would cost $534 to replace the fuel guage sender, however, when they checked further they found the fuel tank needed to be replaced, ended up costing $373.65 since some of the cost was covered by the recall. Haven't had any problem with the service engine soon light.

The actual repair if needed is to replace the fuel tank. I believe they have to (or at least usually do) remove the fuel tank to replace sensor

I'm not sure about the fuel low light/ gauge thing exactly. I do have those problems in mine I suppose. Top half of the tank everything is fine but when the fuel goes below 1/2 a tank then we can never tell how much is in it other than reading the driver information system gallons used. The Service Engine Soon light sounds like an issue we had in our other car(a ford Taurus) there was a small tank leak at the top of the tank and we kept taking the car in to get the error read. At least here in our city there is one place that reads it for free. Our error on that one was below bank 2 or in other words somewhere in emissions. Pressure was not accurate in the gas tank due to the leak. Maybe if this is your issue then you can get the tank replaced(at Buick's expense) and save some money on the sensor repair.
#1970 of 2541 Hayes or Chilton's manual
Mar 01, 2008 (5:37 am)
Has anyone found a Hayes or Chilton's or another type of manual on this car yet? Been looking everywhere hoping to find one but apparently this car is not popular enough to have them go to the trouble of coming out with one yet.
