I did a quick search but did not find anything specific. Here's my problem: The rear window on my 1990 Bronco works when I stick a key in the tailgate but not when I hit the switch on the dash. Here's what I've done so far: (1) checked fuses, (2) checked power to dash switch and switch with volt meter, and (3) traced the harness under dash and inside tailgate for damage or loose connections. Has anyone else experienced this? Is there someplace I should look in the harness that commonly has problems?
