Wiring problems of the 2002 Saturn LS

I own a 2002 Saturn l 300 6 cylinder 3. 0 engine car. In June 2010 I had a throttle body issue withmy car (reduced power, check engine, service engine lights). I took it to a repair shop and it was diagnosed with a throttle body issue. I purchased the throttle body from gm directly and had it installed at an outside mechanic. Not knowing the electrical issues and computer programming issues around this car, I let the outside mechanic do the installation not know all the computer programming issues around this part. About a month or so later I continued to have issues with the same error messages, but this time I brought it to gm, where they diagnosed a wiring issue. Since then I have had it back to gm 5 more times replacing the entire wiring to the throttle body, the electronic control module, and on may 2, 2011 another trip to have the computer re-programmed to sync the new ecm to the throttle body. This past week I began getting an error message (service engine light) for the throttle position sensor. I called gm directly and opened a complaint case number and brought the car back tot he gm dealer now for the 6th time. The prior visits to gm they have told me they won't honor any guarantees because the original throttle body replacement was done at an outside mechanic shop. I can see that holding weight the first or second visit back to gm, but now this is the 6th visit back and they still have yet to completely fix the electrical issues on my car. I have spent over 3,000. 00 trying to get this right to no avail. And I am somewhat stuck since I cannot afford to buy a new car.

This car has been nothing but trouble. I have had to have the drive shaft replaced, the motor mounts replaced, the tail light assembly replaced, the steering assembly replaced and I too have a problem with the dash lights dimming. The technicians at the local Saturn dealership are nothing but rude. They dont fix the problems you bring the car in for and you end up having to take it back the next day or even sometimes that same evening for a repair that wasnt done properly. I thought this was going to be a good car but it has been constant trouble and is constantly in the repair shop.

Electrical system failed without warning, causing the ignition relay to ignite the vehicle. As a result, the vehicle was consumed totally by fire.

The brake lights failed to illuminate simultaneously. Dealership had to replace the brake lights constantly. The problem was traced to the electrical system.
