Which rear window switch wire goes to which terminal?

[tired80]

I've read 4crawler's rear window write-up...this isn't listed there, unfortunately.

My rear window works great from the switch in the cab, but does not work at all from the keyed switch on the tailgate. Upon removing the tailgate cover piece in order to gain access, I saw that the 3 wires which go from the harness to the 3 terminals on the switch (lock cylinder) had been corroded through over time.

I've spliced new wire in, but after trying all the possible combinations, I'm still not able to get the rear switch to work.

There are 3 terminals on the cylinder/switch, labeled "1, 2, and 3."

There are 3 wires to connect: Solid blue, blue w/ white stripe, blue w/ black stripe.

Can anyone tell me which wire goes to which terminal? I'd like to make sure I have these connected correctly so that I can at least rule that out as the problem.

Also, any hidden reason why the interior switch would work great, but the rear switch not at all? Are they dependent on separate relays, or does the rear switch look for a safety check that the front switch does not? I've double-checked to make sure all the wires are plugged in, and even disassembled the lock cylinder/switch and cleaned the contacts.

Thanks!

Have you checked to make sure that there is power to the tailgate window "stuff". There are a number of safety switches that stop you from rolling the window up if 1) The wiper isn't all the way up. 2) The tailgate isn't shut all the way (push in on the drivers side of the tail gate to test this) 3) The tailgate isn't locked... 4) The top is on (there's a bolt that mounts the top that activates another switch...) But I think these all stop both the front and rear switches from working...

Do you have power to one of the 3 wires? It should be hot all the time.

I can take mine apart and figure out the terminal/wire thing, if no one else chimes in.

Yup, the inside switch works, so I think all the safety functions are working.

I'll take a look at mine tomorrow for you, we are talking about the wires going to the key switch in the gate right?

Yup, that's the one. Thanks man. You should be able to see it just by popping the 2 covers off the tailgate. Might need a good flashlight to see the small numbers on the lock cylinder switch.

Here is a FSM w/ wiring diagram also.

I just hope that solves the problem!
