Question-My 97 QX4 has an issue with the door mounted window switches on the pass. side front, and driver side rear. They will not operate the window, whether the window lock switch is depressed or not. However, the master control on the drivers door works them fine. Any ideas how to troubleshoot this? Its obviously not a fuse issue, or they wouldn't work at all. The lock switch seems to work on the other rear window, as does its respective door switch. I don't want to tear into each door unless I have to. But, if I do, is there a special tool used to get the panel on/off?Thanks,
