old thread, I know
New guy here! Well i've got an 02 and I wanted to do this rear window switch mod. Wired everything in correctly, and the switch kind of works.
My problem is the window only goes down using the switch if the truck is unlocked (specifically only the rear door needs to be), and the window only goes up when the truck is locked (again only the rear door needs to be). At first this made no sense to me, but then I realized that when I turn the key in that back lock cylinder, it locks or unlocks the door before moving the window 3 seconds later (depending on the key turn direction respectively). This is accomplished mechanically via a rod to the door actuator mechanism.
I've only read of one other guy with this same problem but he didn't know what to do either. My best guess is it only applies to 02 4runners, and maybe 01s as well. Why Toyota, why did you change it?? :smash:
Does anyone know of a way I can get around this, other than using a double pole switch that also sends a separate signal to lock/unlock the doors prior to moving the window. Any suggestions are, of course, much appreciated!
