Okay, I've read everything I can find on fixing a non-functioning dash switch on my '89 Grand Wagoneer on the forum and in the Tech Library but still can't get it to work.
Here's what I've done so far:
1) The key switch was broken so I repaired it using the repair shown on Ipendia - Grand Wagoneer Rear Window Switch. The key switch now works perfectly.
2) I've pulled the dash switch and checked for power at the plug. I can get power to the purple/red wire socket. The there are four other sockets (brown and tan and two black ground wires). When I check the brown and tan wires while pushing the switch up or down I get power. I've even clipped the test light ground clip to both black ground prongs in the plug (pulled the switch part way out of the socket to do so) and everything works as it's supposed to. So I have good grounds at the switch.
So I have power at the dash switch and at the tailgate... but the window still does not respond to the dash switch.
Everything else at the tailgate works... wiper and defrost. I've completely gutted and cleaned out the tailgate. The dash switch worked about 10% of the time before gutting it... but I think that had to do more with the broken tailgate switch.
Any suggestions?
Thanks.
