Where is the power window relay switch on a 1993 Chevy Blazer S10 Tahoe 4x4 I have located the fuse and changed it however that had no effect. All windows stopped working at the same time so I am baffled at the cause. I cannot locate the relay so I wanted to eliminate it as the cause before i start running wires down to look for a problem there (the one that controls all 4 windows)

 

From what I know, there is no relay. If all the windows just stopped working, I would guess its the main switch on the drivers door that is the problem.
