Did you ever save an old one to "play" with? If you have to replace it,
you can't break something that is broken is my motto.  :-) Some have
contacts you can get to and clean. Seems like the drivers window is the
only one you can't fix because of the electronics for the auto down
feature.

There is no way to fix the switch since the contact points are what
fails.  Seems that water makes its way into the switch and corrosion on
the switch contact points is the result.  If you could tear it apart you
might get to the points without breaking the rest of the switch.  I am
on my third switch too...

I just bought my first replacement from a junk yard.  They let me install it
right in the parking lot before I paid for it.  It worked fine, so I gave
them the $25 they wanted.  Seemed like a cheap fix to me (it's $125 at a
dealer).

I have removed and completely disassembled it trying to clean it up so the
driver's window would work.  It did work for about 3 months, and then failed
for good.

Find one at a junk yard if you can.  '89-'94 SE and GXE should all be the
same for this part.  You'll get the entire assembly, buttons and all.  I
mixed and matched the best looking buttons and put them on the new switch.
Works great, and looks better than it did.
