Cold Hot Weather Power Lock Issues

Hello everyone,

I have a weird power lock issue. My 2009 Cobalt driver side front door will only open with my keyless entry remote when it's cold.

Early in the morning when I press the unlock button all the doors unlock, but once it gets hot the driver's side tries to open but it will stick and just move a little or halfway up, either way, I have to use my key to open the lock.

Has anyone come across something like this before?

Thanks in advance.

Weak solenoid or it's gummed up. Try cleaning and lubricating.
