So I've been stumped on this for about a year and half now.
So here is the problem.
My passenger front window switch won't work to roll the window up and down but I have control on the main driver panel. Now I have checked the window lock and also bypassed it like other posts have said to see if that was the cause but still no luck. All my other windows work accordingly by themselves and under their own switches except the passenger front.
Now here is the tricky part I've come to realize that we all know the switches themselves light up but that one specific switch for that window button doesn't.
I have already bought a main driver switch panel & passenger switch panel with no change.
I checked the fuse and it's good. I've checked the wires and yet still no cracking or splits. I even electrical taped them up after removal for safety.
I have no idea what color wires are the power wires I need to track down.
So if anyone can tell me the color wires to track down that'd be AMAZING!

 

I had similar issues, and was planning to rehab my switches—until I saw they were $20 new on Amazon. They’re working fine now.

 

I took both master switches, drivers and passenger out and retouched all the solder joints. Everything works perfectly. Took 45 min.

 

So you bought a wire harness for yours them swapped them out and it's worked out good? @RAGordy

 

@Lynn Gräber but what if I have a new master and passenger switch already in? I know my jeep is salvaged from the passenger side getting crunched and then repaired. I bet you they wired it up wrong😬
