Hi
so I’ve worked on cars pretty much my whole life just when things broke down on my own cars. But recently I have found a new love and hobby of actually like working on cars. I bought a 1984 Chevy S-10 blazer for a really good price. It runs and drives great. But the windows don’t roll up or down. The fuse to the power windows is good. I changed out the passenger side window switch, nothing. I haven’t changed out the master switch yet because I have to order it.

Just for some additional information the windshield wipers don’t work either which could mean an electrical issue? Any help would be greatly appreciated!

 

Do you have a digital multimeter and do you want to diagnose the problem by tracing the voltage and ground signals?

While I haven't done this in an s10, when the window quit moving in my folk's suburban, I unplugged the cable from the window motor and measured the voltage at the cable leading to the motor. We were getting + & - 12V to the motor when using the window switch, so it was a motor issue. If you get yourself a multimeter, and work backwards from the window motor, you should be able to find it in no time.
