Rear bed window going down by itself?

The last two days at work when I come out to my truck the large rear window to the bed has been down. This is a 2019 SR5 four door. I don't lock my truck at work as it is a secure lot. I also noticed when I remove the key the window up/down switches on the driver's door still work.

It could be a co worker messing with me but I really doubt it as they don't mess with other guys trucks.

 

Does it only happen at work?

 

Locking your truck would be a great place to start.

 

Yes, which makes me wonder if someone is screwing with me. I didn't think the switches had power without the key on acc. Also my fob has no button for windows either.

 

I don't lock it as there is an another Toyota that parks in the same lot and my alarm goes off occasionally and I think it's because of the same key fob frequency or something? I haven't seen them lately so I guess I will start locking my truck and see what happens

 

I park in secure parking both at home and at work, but if I'm not in the truck, it is locked.

 

This is at a police department by the way so that's why the lot is secure. There are entry gates with a pass code / card

 

Oh yeah cops never joke around! When I’m at work at the FD I worry more about the guys inside the PD than the ones on the street (shared PSB)

 

Ok, I just sat at the park for lunch and after 5 min with the key out the switches are dead. I do leave my keys on my desk so I think there might be some @#ckery going down. Time to park in front of the security camera

 

My 2017 1794 does the same thing sometimes. I figured I might have hit it with my knee or something. I check it now every time I get out to make sure I roll it up.

 

If it only happens in one location, it isn't the truck....... And I don't care if it is a "secure lot", lock you damn truck and don't leave your keys out in the open.
C'mon, get a little smarter than that. I'm sorry, it had to be said.

 

All of us CM owners are bitchin because we don't have the auto down feature on our bed window. What's your secret?

 

You get the most random stuff happening to your Tundra lol

 

Iowa/Bermuda Triangle

 

Don't forget Arizona in the triangle.

 

Umm yeah, I am living in AZ now and I think I am parking it on top of an Indian graveyard and feeding the gremlins after midnight or just living wrong IDK? When I lived in Iowa the battery on my vehicles would die whenever I parked over a spot in the side drive of my house. I don't know if it was a magnetic vortex or underground electrical attenuation . I could put in a brand new battery and park over that spot and it would be dead the next morning no matter what vehicle.

 

Reminds me of my old Honda. The cigarette lighter socket shut off with the ignition but if i plugged a portable cooler in and shut off the car the doors would unlock every five minutes like clockwork. Weirdest darn gremlin i ever did see

 

I'm quite sure the rear bed window isn't going down by itself, but someone has your RF for the locks and rear cab window.

 

Tie dental floss from the shifter to the door handle. Exit from the passenger side.

 

There are ways for windows and the sunroof to be opened w/the key fob. I believe in my 2019 4Runner, I could roll the back window down by holding the unlock button down for 3 secs. I believe this is a dealer programmable feature in some models. Dealer may be able to turn this function off, or you just might need to be more aware of your key fob buttons being pressed accidentally. However, as others have said, this may be mitigated simply by locking the doors.

Good luck

 

Both my brothers have F150s. Both have come out to their trucks with side windows down but it was due to Ford's quality window parts.

 

Ok, it hasn't happened since I posted last week? I am tempted to call shenanigans. Ford used to have a feature where you could click the fob three times and it would put all the windows down. I kinda wish Tundra had that.

 

Sounds like you need to set up a sting operation with come bait keys and a camera.
