Hello im having a problem with my power locks, i've seacrhed but cant seem to find a similar problem. Early morning when temp outside is cool all my locks lock and unlock perfectly, all four doors. But when it warms up outside everyday, only the drivers door unlocks. All doors still lock, but only the drivers unlocks with fob & switch. Later in the evening when the temp cools again everything works again. Call me crazy to think the outside temp is affecting only 3 of my doors? and only unlock? Help pls. Also i dont know if this is revevent but every once and a while my window lock switch will turn on. Not sure if its me hitting the switch by mistake or relevent information. Thanks again.

Your CRAZY!!! J/K

It sounds like a bad connection that could be an expand/contract kinda thing that is temp related.
I would start at the wiring/connections on the driver door window/lock switch. If all is good there, maybe a bad wire in the harness between the door and body.

I would say that the window lock is just being accidentally pushed.

 

Yeppers. Remember metal contracts expands with temps. It could be just enough to be giving you your issue. Its rare but possible.

Welcome to the site

 

i used to have a problem like this in the winter time where the doors wouldn't unlock with the remote but once it was a nicer day they would i have an auto start system in mine and its garbage cause now nothing works and only 1 of the 4 doors will unlock with the switch now it really bugs me but i haven't had the patience to take my doors apart and trace wires to see if its my door poppers not working or what.
