How can I still roll the window up and down if the windows are dead? I'm confused I assume that the master switch and the other 3 door switches act something like a two way switch in a house, where certain faults would kill the whole system - such as an unplugged master switch, which I assume prevents power from going to any of the windows. But I'm guessing without a schematic.

OK, status update. I removed the master switch. I unscrewed the top black cover. I removed the bottom plate covering the traces to the wiring harness socket. I have a meter and know how to use it but I don't understand the wiring of the switches at all. Is there a schematic available to help me understand the correct opens and shorts in various positions? I found two contacts under the window switches that are closed when the switch is at rest and open when the switch is rocked to the up or down position. Other pairs open or close depending on the position - raise or lower. As near as I can tell the bad switch (that does not raise the right side passenger window but lowers it) seems to behave like the other switches. Unfortunately I used a continuity checker and did not measure ohms (keep reading). However, it is probably tough to get good contact on the pins to get a reliable reading. I cleaned the switch, getting a lot of accumulated junk out but there are a lot of nooks and crannies under the switches. I blew canned air under the switches to blow anything loose out, plus whatever I loosened up in cleaning. I sprayed contact cleaner under the switches but it does not appear as if the actual metal contacts are accessible without removing the last piece, which I do not want to do (unless advised) because I don't know what will go flying out. And I don't see any obvious problem with the switch. The cable harness plug contacts and the switch contacts look fine... I don't see any signs of obvious corrosion, especially on the plug and socket since the switch itself seems to be ok. I know that switches can develop resistance without appearing badly corroded so I sprayed contact cleaner on the wiring harness plug and socket contacts before reassembling for a test, and I disconnected and inserted the plug 3 times to try to scrape off any hidden surface corrosion. All that cleaning did not materially change anything. However, when I first installed the switch it operated the window very weakly and feebly for a few seconds. If I press down hard on the switch (probably harder than is healthy for it) I get a very weak response in the raise position. I think that suggests that despite all my testing there is likely a problem in the switch itself? Any suggestions would be appreciated. Thanks for your indulgence, Neil

Thanks for all the quick responses! I'm not very optimistic about this. I think the switch has gotten wet a couple of times over the years and what I really meant was corrosion not dirt. However, some people experienced miracles and reported it here. Could even be a loose plug. Hehe. I figured I would give it a try since I wasn't planning on paying full boat for a new one. For $135 I'll lean over and hit the passenger switch :-). I tried spraying contact cleaner down from the top into the switch. That did not help (and didn't think it would). Silverton- Unless a miracle occurs over the next day or two I will take you up on your very generous offer! I appreciate that. You are a gentleman and a scholar Best, Neil

I'm new here, with a very basic question. Humor me I need to remove the Master Power Window Switch on a '91 Pathfinder SE-V6 for cleaning and inspection. The right passenger window will go down but not up when using the driver's master switch. The passenger side switch works fine in both directions. From research here I need to check the plugs, clean them and maybe try to get some contact cleaner in the switch? Do I just pry the switch up from the arm rest with something like a putty knife? I''m asking before I break something I'm the original owner of this Pathfinder. It's been good to me but the years have taken a toll, especially since it's never been garaged (no room- my '85 RX-7 still has that spot). Thanks, Neil
