Power window not working


#1

Hi, I have a 99 Crown Vic. The power windows work on and off. One window may all of a sudden stop working. A day or two later, it will work again. This happens to two of my windows. What should I check? Thanks.

Check the switches, using a wiring diagram and a voltmeter.

Also check all the wiring connectors. Look for loose or corroded connections.
