My car's headlights turn on and off and wipers turn on by themselves when the car is turned off and when I try to open the door with a remote it won't open. I have to use a key.

Hello,

It sounds like the PSE (Pneumatic system equipment) has gone out which is located under the right rear seat. This will need to be programmed in which should cost about $130.00.

Check out the diagrams (below). Please let us know what happens. Cheers, Ken
