Electrical problems

When I step on the brake, the rear window wiper turns on, and when I let up it turns off - it doesn't matter if the car is on or off. I went to get in the car and the heater blower was running and I hadn't even turned the car on; plus, the driver's side front and rear turn lights stay on and runs the battery down. Can anyone tell me what I need to do?

    Sounds like a short or more than one for sure. Going to have to try to isolate things by pulling fuses to try and diagnose things.

    Technicians sometimes call these an "Edison problem" and they can be tricky to solve. Somehow you have voltage bleeding from one circuit to another, or grounding a circuit on its own.

    Best thing I could suggest if you consider yourself handy enough is to get a complete wiring diagram for the car and try to trace where the devices affected intersect with each other.

    Another long shot short of going to a qualified technician is the "jiggle test", where you move various wires or harnesses while the event is occurring, and see if it stops and starts as you do this. That at least might localize the issue somewhat, to underdash wiring or fusebox wiring perhaps?

    You might scan the website shown below here, and see if there's a specialist near you:
