I have a 1994 S500 coupe that is having a problem with the drivers side power window. Some time it doesn't work, and the lowering and raising of the windows when the door closes doesn't work either. I kept wiggling the switch and it started working again, but there is a problem with the express open and close. I think that it is just the switch, but how do I get it out to clean/replace it?

The shifter wood comes out & switch is clipped onto it. The switch only sends signal to window computer in trunk.
