rear window key switch

[Celltender]

So I have a 2019 (5th gen) 4Runner, my liftgate window has worked both from the console switch and by turning the rear key in the lock since I bought it. Approximately one month ago the window stopped working when using the key but it still works by using the switch in the console. I have the Carrista and double checked the hidden features, everything is fine there. I also have a BlueDriver so I checked for codes, I did get one that read “B2312 - ON SWITCH FAILURE”, upon further checking on that it appears that code is usually referenced to a bad window motor or regulator but I find that hard to believe since it works fine from the console switch. I did notice this stopped working shortly after getting the car washed. Any ideas for repairs? I have been leaning towards a liftgate key switch but they aren’t cheap so I figured I would ask you gurus first!

OP, I took the post you made in an existing thread in the 1st Gen section and created a new thread here in the correct gen section for your year vehicle.

You should be able to eliminate the key switch as the culprit by either substituting another switch (just about any switch should do) or by removing the plug from the switch and making a jumper to make the connection. The window motor should then run. Since the switch in the console works - I'd start my test with the window half way up. Getting access to the switch and its plug will be a pain, but you're probably headed there anyway, and you'll be able to see if everything else is ok in there.
