My turn signals werent working. I replaced the flasher relay, and still, nothing. Im gonna let a mechanic work on it. But I was wondering if anybody knew what it was. Mabye I dont have to let him work on it.

Also, my window switch was all screwd up. I bought a new one, and my back window isint working. Not even from the back window switch. Could it be a motor?

Hi,

Check your turn signal switch. The one that's also for the wipers and the hi-beams. They fail more than most people realize. Also, obvious as it may seem, check the fuses.

As for the window situation, the surest way to check if its the motor is to take off the upholstery back there and unplug the electrical connection to the motor. Then plug a voltmeter into the wire and press the window switch. If you get current, it is the motor. If not, maybe another fuse blew.

Hope this helps.

Replace the hazard switch. This is almost always the cause. Cost is about $15.

Hope this helps....
