I was just given a mint 1994 S-10 Blazer.

The thing runs like a top, but 3 out of 4 power windows do not work. Odd. I have never seen that many break in all of my years of owning Blazers. I don't think it's the motors. The electrical connections that I see are good. (Remember this car is mint).
Any ideas? Relays that I don't know of ??? Thanks !!!
