Ok, my driver's side window hasn't worked since I got the car almost an year ago, but it was winter and I figured I wouldnt need it, but now I took out the regulator and the motor for my driver's side, I tested the motor from it by hooking it up to the passenger side wire which did work and it didn't work so I figured it was the motor, I went inside and cleaned the contacts with some Noxon-7 its a metal cleaner, I tiried it again, this time back on the driver's side and it magically worked. I was beginning to put back the regulator and everything in the door when I hit the button to test if it still worked and the fuse blew. I tried another fuse and again, same thing. I tried yet again this time thinking some wires had been touching that were exposed so I covered them up with electrical tape...but nope, still blew another one. I don't understand what is going on. I thought maybe it was the driver's side fault so I disconnected it again, but it still blew. I have no idea what to do, I can't keep going through all these 30 amp fuses. Do you guys/girls think its the cleaner I usesd? It has ammonia so it might be conducting a circuit between the 2 contacts and causing a short circuit. I was so happy that the motor was working finally, now this.
