I had a similar problem with a 2001 GM four door.

I tried cleaning the window switch contacts but that didn't work.

A brand new switch from eBay did the trick and now all the buttons/windows work great.

The driver's window switch also is the receiver for the remote entry system.

Putting a new master switch in, should it need one, will require reprogramming all the remotes (fobs) to the car and resetting the driver's window auto function.
