I've been having a continuous problem with my power windows and power door locks. In detail, my passenger side window will not go down, but will go up. My other windows work as long as my driver's side door is closed. My driver's side power door lock only works only when it wants, and that usually corresponds to when the auto down feature on the window wants to work, too. I've taken apart the passenger side door to see if the motor is done, but all electrical readings are normal. Back in october of last year, i did manage to (stupidly) leave my driver's side window done when it rained and i know the switchboard for the windows got wet. Any ideas on what the problem could be? I'm hoping it's not the BCM and just some sensor somewhere. Thanks

 

Most of the problems seem to have one thing in common --> Driver's side door <--

You mentioned rain into the door .... perhaps corroded connections on the switchboard, or maybe even broken/damaged wiring inside the door.

With respect to the passenger side -- again, a loose or corroded connection could be your culprit

 

Change the main switch and go from there.

 

Try removing the driver side control switch.
Then before you go out and buy another one, get a can of electrical contact cleaner.
It may be a tiny amount of corrosion that is causing your problem. Liberally clean all contacts, connections in your drivers side door.

And you can never be too " methodical" about doing this. electrical wiring has its moments

What were (are) the results of your forage into the innards of your driver's side door and the window control circuits??
