I'm having an issue with my Rear Hatch (Tailgate) Window - the
center console switch is not working. The
rear-hatch key DOES work to roll the back hatch window up and down.
I just swapped my rear hatch trim piece (with the "4RUNNER" logo on it), and had to disconnect the harness that feeds it (has the rear key switch and license plate lights on it). Additionally, I had Dynamat all over the rear hatch's inner skin, and had to cut through it to access the innards of the rear-hatch (to remove the trim piece).
I'm 95% sure I didn't cut any wires by accident - so is there something else I might have knocked loose while I was in there?
I'm a bit stupid on the FSM diagrams, but I see in the FSM Diagram section that the Rear Window
rear-hatch key switch (1st pic below) seems to interface to the "
Multiplex Network Door ECU", as does the
center console switch (2nd pic below) (I believe this ECU is in the main cabin somewhere - NOT in the rear hatch). (RED Borders and Yellow Notes are my additions).
Then the "Multiplex Network Door ECU" sends commands from either input (switch or key) to the "
Back Door Power Window Regulator Sub–Assembly" located in the rear hatch (also in the 2nd pic).
Seeing that the rear key works up/down, it would not seem that I cut any wires feeding the "Back Door Power Window Regulator Sub–Assembly" as that would probably mean neither the
key or
console switch would work - is that correct?
I do see one wire that directly hops over from Center Console Switch to the "Back Door Window Regulator Sub Assembly" (ILL+ to LED), but it appears to be an LED trigger?
Any clues on where else I should be looking? It is obviously something I did to the rear hatch when I was swapping the trim piece - but after double checking everything 3 times I just can't find the wiring issue.
Thanks all!
