2004 Silverado Ext Cab Power Window Switch

[LBJ]

I am looking for a replacement switch for part number AC 15112969 which is the ganged switch for the mirrors, windows, and door locks. I checked to make sure the motors were still good and that leaves the switch being balky. The switch has gotten progressively worse over time to the point it barely works for the windows. I pulled it out and blew it out with a high pressure air hose and that might have done some good, but it's still balky. Would a spray of contact cleaner help any? Of course, totally off the truck and given time to dry out. Replacements are quite pricey $120 or more plus a core charge on Dorman 901-292R part of $200. Thanks, LBJ

Also, I've looked on Rock Auto, E-Bay, Amazon, etc. All parts are about the same price. Rock Auto might be the end choice if it cannot be fixed with a contact spray cleaner as I have a 5% discount there.
