Wierd Electrical Gremlins 2000 Gnd Marq LS
Here's a stumper. About a week ago I found my car had a dead battery. Tonight I went out to the yard and found all my lights on, cycling on and off about once every three minutes. The car was locked and factory alarm was armed. I opened the car, switched off the auto lamps. Locked up the car and waited. About two minutes later the dome and interior lights came on again and started the same cycling pattern. I think this is what killed my other battery! The car is new to me, it was traded in and I'm guessing now, I know why!! Any clues?
