Sounds as if they repaired/replaced the intermediate steering shaft. Sometimes, if care isn't taken, the steering position sensor can be damaged in the process. Generally, that would happen before a year went past, however. There is a lengthy TSB on replacing the steering sensor, and I could see where 2 hours may be the established labor time.

2 hours is what they quoted me to figure out the loss of power in the other 3 doors actually. Another detail of the Traction Control and ABS lights coming on and the Service Stability Code appearing at the same time is it only happens when I start driving forward. I can leave it idling for minutes and nothing...as soon as I start moving forward it throws the code and sometimes starts acting as if I am on an icy road with the ABS kicking in for the first minute or two of driving. Steering and braking is fine otherwise. No clunks when steering.

Forgot to mention, I am certain these cheesy dealers would have simply greased the shaft to rid the noise or whatwever that cheap fix was I read about. They would never have replaced it, cost too much time and money and for the most part that seems to make the problem go away at least until it'* out of used car warranty anyway.

The fact it doesn't throw the code until I start driving forward lead me to think it could have been a wheel speed sensor, I will have to read more about it

It could be the wheel speed sensors. The dealer can scan for that. The stability system uses the steering position sensor, the wss, the lateral accelerometer, and I think one more that I don't recall the name of to check which direction the car is moving, and if it is in the intended direction. A fault in any will trip the error, and of course it doesn't know anything until you start moving.

Yaw rate sensor provides yaw rate error (based on steering wheel position sensor input), a measurement of oversteer or understeer. wug, when this ABS phenonema occurs, does it seem like either the left or right front wheel brakes are being applied? Or is it too hard to tell? And I'm assuming that you are not using the brakes when this happens.

Would never be able to tell because yes...I am applying the brakes when this ABS freak show occurs. This only occurs when I apply the brakes, however slightly (usually when coming to a slow stop at a stop sign). It does not last more than a 2-4 brakes or about 2 minutes. I reverse out of my driveway, and a second or two after tarting to travel forward the Service Stability code spews and the trac and ABS light come on. I have only noticed the ABS actually seeming to kick in when I stop.

Hi. New to the forum. My 2001 SSEi is experiencing the same loss of power to the two rear doors and the right front. The link to WUG'* initial thread posted by Archon appears to be cut off (http://www.bonnevilleclub.com/forum/...199&highlight=). I wonder if someone can please repost the link in its entirety so I can reference it and try to solve my similar door issue. My understanding of the advice given thus far is to check the ground under the right front seat and to also clean the negative battery cable connector. Is this correct? What about the fuse in the rear fuse block? I am not a mechanic, so how do I identify which ground I need to check under the right front seat? Thanks in advance.
