I bought a 2001 Cavalier at the auction last week. It runs well, but we've got one small problem, no lights. Here's what happens:
1. Start up the car, put it in gear, daytime running lights(DRL) come on, no problem.Turn on the lights and the DRL goes out.
2. Car drives fine. DRL is on, yellow side lights are on but if you turn on the lights, the front lights go off but I do have tail lights.
3. About the 3rd time you start up the car, the DRL indicator flashes quickly on the panel, the service light (NOT the check engine) light comes on and the DRL's go out.
Went to AutoZone to have the service light read and it came back with a P1621 Error - something like Immobilizer codes does not match.
Roommate and the guy @ Autozone thinks it's a bad key but I'm not sure. Could it be the DRL Relay in the fuse box going bad? The car has manual locks and windows so I can's see it having a theft system on it. Anybody else have a guess??
Update - replaced the lights and the relay - same problem. Socket that the lights fit into doesn't make sense - 11 volts when on, 0 when off, but the lights don't come on. WTH?
