1st Gen - Rear Window Key Cylinder Stopped Turning Left (Up)

Hi guys,

A few days ago, I noticed I could no longer turn the key in the rear window lock cylinder to the left to put the window up. Down/right is fine. The interior front console switch works fine in both directions.

I can't recall when it was working, if the cylinder always turns left, and the window won't go up (i.e. when the top is off releasing that bolt switch), or if that switch prevents movement of the lock cylinder completely?

Basically, is this a physical problem or some weird wiring issue? Not sure where to start here.

Just mechanical issue with the cylinder.

When working, the tailgate key switch simply connects Pin 11 or 12 of the window control relay to ground to roll up or roll down.

Toyota components are bullet-proof. Issues often arise from poor wiring, assembly and/or maintenance. Suspect those first.
Next only to our senses, the multi-meter is the most important electrical diagnostic tool. Spend $6 at Harbor Freight or $$$ blindly replacing parts.

sounds like an issue with the switch itself. you may try some lock cylinder lube, or compressed air. if that doesn't work, you will probably need to replace it.


the last time I checked, they were fairly expensive.

Someone on Yotatech deleted his tailgate roll-up window. I think Cory. Ping him in case he still has the switch.

Yeah mine is the same way. IT still works though if I put the key in then back it out just a hair width, then it works fine. I'm so used to it now I do it quickly and without much jiggling. Mostly I just load up and use the inside switch though.

All,

Thanks for the suggestions. I used some 3-in-1 dry lock lube and it didn't help. In fact, it made it worse, now I can't turn the key in either direction. Looks like I'll be removing the entire assembly and troubleshooting. I wish this happened before I completely sound deadened my tailgate. This will not be fun in freezing temps .

I did find a detailed write-up on here that I'll use to get at the switch itself:

Tailgate Lock Cylinder Repair (walkthrough)

Also, I have an extra switch but I have no idea of its condition. Luckily the interior switch still works fine.
