My drivers side door is having some issues electrically..

Window, Mirror switch, and power lock on the driver door only work when its 90+ degrees out.

It's not the switch, brought it to a local mechanic recently and he tried multiple switches with the same issues...

What should I look for? going to pull the door apart and check the wiring, but does anyone else have ideas / similar experiences?

Thanks,
Dave

The drivers master window switch is actually a module that requires a software download if you replace it. This might be the issue

 

I have the original switch still in the door.
