Hey everyone

Just signed up seems this is gonna be a great place for me!
Anyway I have a 1997 Blazer lt that i have had since new. The other day I went to open the sunroof and it only opened part way the stopped and started to make a clicking sound, wouldn't go forward or backward. I then tried to close the Dr side window and it would't close either nor would the other window's work!!!!!!!!!! So I tried
pulling on the Dr side window and it started to work along with the sunroof.
Shortly after I was brave enough to try it again and the same thing happened! Pulled on the window and everything started working again!

Ant thought's , I am thinking maybe a relay?
