Not really truck related but more GM related. I have a 93 Olds Ciera and a 97 buick Skylark both seem to have intermitent problems with a window rolling down but then when you go to roll it up it is like the switch doesn't work for 10-30 min. I can push the switch to go up and nothing happens no noise from motor, just nothing. On the buick it is always the front pass window and on the olds it is sometimes either of the front windows and sometimes the rear pass window. Just wondering if this is common and/or where I should start looking to find the problem. I am hoping maybe it is just a bad window switch or relay but don't really know. Any ideas?
