I have a '99 Trooper with a strange power window issue that just began. All my windows and locks work but the master power window switch will only operate the driver's window and the door locks and will not operate the other windows. Each individual door switch works and will operate the window for that door. I have now twice replaced the master switch and each replacment switch does not fix or change anything. The first switch was from a '95 or '96 that I pulled myself, so I figured it could have been a bad part. I just bought another one online from a '98 that I was told was tested and working, but again the same issue. Am I missing something obvious here? Do I need to try a third switch? Could the relay be defective even though the windows work? I even re-soldered every contact on the circuit board but to no avail, and have sprayed contact cleaner on the connectors. This issue started around the same time that the TOD began having issues. I've been searching the forums for hours but haven't run across a similar problem. Thanks for any help!!
