Pontiac Repair: Grand Prix GTP 99, grand prix gtp, grand prix gtp 99

Question
I drive a 99 GTP. My grandprix has had both front Wheel Barrings changed... TWICE. I changed my brakes, and I have took it in for a Diog. No one can tell me why my 'ABS' and 'TRAC OFF' lights are on all the time, but Lately I also felt my power steering to start  going a little bit on some turns then it would go back to normal. Now my cruise control dosent work. Seems like we are all having the same problem. Can anyways suggest anything?

Answer
Hi Jaber:

what codes are setting on this? were the hubs replaced withe origianl equipment parts or aftermarket? These cars were noted for wire harnesses going bad ot the hubs that could be the issue here.. The power steering is controlled by the ABS module so if there is some kind of control module failure that is turning the ABS lamp on it could affect the manga-steer system this car has.. Unlikley but pssable.. As for the cruise control it could be a lot of things from a brake lamp switch to a bad swithc on the steering column to the control module for the cruise.. withe out the aid of a scan tool that is hard to figure the issue out.. In some cases a service engine soon lamp on for the engine could turn of the cruise... I assume you don't have a lamp on for that because you didn't mention it.. The cruise control on that car is pretty complex for what is does and any one of the things mentioned could be the issue... There is not 1 common part that goes bad for those it's pretty much all over the baord as to what the failures are no common thread.. Good luck :)
