Went to the pull it yard yesterday to get a replacement switch for the driver's side rear window as it wasn't working. The window is fine using the center console controls, but doesn't work with the switch in the back. Put the replacement one in and nothing. Still didn't work. Is there any way that I can test the wires themselves? Maybe jump the terminals in the connector block and bypass the switch to see if it works? How should I proceed to diagnose where the problem is? I do have a DVM so can test 12v and continuity...

 

The first thing I would do is check to see if power is getting to the switch. Then go from there.

 

Is there a pinout for it so I know what wires to test?
