Power Window Issues in 2007 Tacoma

I've just hit 60K in my 2007 Tacoma double cab, and I'm starting to run into electrical issues. First thing to go was my A/C switch, then my passenger front window switch started to work intermittently, and now my passenger rear window went down, but now it won't go up.

I've checked the fuses (which were all good), and I tested the power going to the window motor in the passenger rear window, and it is getting power (I used a multimeter). I don't think it is the switch because the window doesn't work with the driver window switch either.

Could all of these problems be related, or am I just having horrible luck with my Tacoma at the moment with three seperate problems?

 

I doubt the AC switch is related, but the window issues sound like a bad master switch. Not sure how the Taco is wired, but recently fixed a Dodge truck with the same issue. One window would go down, but not up. Didn't matter which switch. If I remember right, the ground for each passenger window motor had to go through the master switch. The taco is probably similar.

If the motor moves in the down position, it's fine. If you were to reverse the two wires at the motor, then push the switch down, the window should go up. If so, you have an issue in the wiring or switches.

 

my passenger front window has the same issue with the switch. It sometimes doesnt work.

 

I do know the fuses for the power windows for each door only control the master switches on the driver door, so I'm assuming you are correct, that the other doors must also wire into the master switches in some form or fashion. I'll take a look at the wiring in driver door to ensure everything is connected securely and receiving power. I'm a novice electrician, so I"m like a 5yr old kid trying to grasp world politics, but we'll see how this goes.

 

The DC's have a history of problems with the passenger rear window going down but not up using that door's switch (it does go up with the driver's switch). And frequently you can move it up a little bit with the driver's switch and that rear door switch will work again.

Had this problem years ago and the dealership replaced the switch in that door under warranty. Still does it even with the new switch. I've run across many others in the various forums with this same window having this problem. Why it's only the passenger rear window is beyond me, but maybe it's just that the driver's rear is almost never operated by anyone sitting back there (my daughter always sits on the passenger side)? And it's usually only a problem is the window is down all the way rather than partway.

So if you figure out what the problem is, post back. I've had that door panel off in the past for other reasons, and I don't know why I didn't think to look into it while I was in there! I guess because it doesn't bother me. If my daughter can't roll the window up from her switch, I just do it from mine.
