instead of complaining, i'll list what problems i've experienced with my 155xxx mile 2000 grand prix. i'll list what i've done to fix those issues to help others out.
1. ignition key getting stuck in ignition
1a. fixed with some zip ties after i tired of using a screwdriver to take the key out everytime i used the car
2. taillights and brake lights had no power but the cal light still activated
2a. fixed by replacing faulty hazard button
3. rear passenger side window stopped working
3a. fixed by replacing regulator due to the original cable wore through the plastic. imho- the factory should have used a pulley instead of just wrapping the cable around a piece of nylon/plastic
4. intermittent stalling P0102 code tripped
4a. fixed by replacing the maf twice since the replacement maf's were bad too!
5. driver side window only rolls down
5a. metered out wires- reversed voltage with test leads to roll window back up- conclusion- replace switch (looking for used switch)
6. heater blows cold
6a. not fixed yet... replaced heater core and heater hoses something else is still clogged. ***update 10pm cst- heater fixed. the return on the engine was also clogged http://www.grandprixforums.net/heater-core-41629.html
7. wheel bearing noise
7a. replaced driver side wheel bearing
