When I first got my car, the power door locks worked. All of a sudden they stopped working. If I remember correctly the fuse had blown. The fuse that was in the fuse box was 5 or 10 amps higher than what it was supposed to be. I replaced the fuse, and the power door locks started working again.
Well a few weeks ago I pushed my power door lock button, and it had stopped working again. I checked my fuse, and it was fine!
What else can I check?
