Chevrolet Lumina Problem
Visitor, 1994 Chevrolet Lumina, 172,245 mi
window rolling mechanism that glides the window up/down worn out, causing it to wobble in the glider or stick, thus window pitches forward and window rolls up crooked. I had to replace glide mechanism and use white grease to aloow it to run smoothly

This will be the second time I have had to replace this switch. I bought a replacement the first time, but I am having trouble locating one this time. I don't intend to spend a lot on this again.
