Weird electrical problems, I have taken to 2 different people, 1 of which specializes in transmissions, the problem is that when the vehicle is warmed up the transmission doesn't know what gear it is in, on initial investigation the problem appears to be the trottle position sensor but that was replaced and still no fix. They hooked up computers to the car while driving and say the computer doesn't read the tps being operative during driving but no problems can be found with the wiring and computer board. When the engine transmission starts to mess up the locks start to lock and unlock by themselves while driving, the check engine light is on and the overdrive light blinks off and on. At one time the air bag light come on for no reason it was checked and problem found. The sliding door latch broke within a couple of months of buying. The back windshield wiper motor would also come on by itself, we ended up taking the fuse out for that.

Dealership fixed lock problem, but then refused to fix alarm problem after car was paid for. They told me it wasn't their problem, and that it would cost me about $500 to fix it. I couldn't afford to get it fixed right. Can you help me with this problem.
