Whenever I start my disco, the drivers window always goes down on its own. Anyone else have this problem?

 

Yes, we all do, that is the "fly" feature, it is to let the flys out of the truck.

Sounds like you might have a bad window switch. Remove the panel that houses the window switches and unplug the drivers window and see if it still happens.
Just for fun plug the passenger window into the drivers spot and see if the pass window does the same thing.

 

How do I get the switch out?

 

Hell I dont know.

The cover should just pry out and then the switches will be in the cover.
These are the wrong switches but it will give you a visual.
