got a 1997 S10 blazer that i was just given me by my friend. thing is he had it in his garage ans had all the windows down while he was doing a motor swap in it I went to pick it up and it has power everything and since the motor is out everything is unhooked and now I cannot roll up the windows again.

I have read that there is some way to roll them up by jumpering across the switch contacts and after reading my chilton manual i know know which wires are for what. but not sure how to go about this any one have any idea how to roll up the windows without burning up the computer or anything electric?

Any help is appreciated and thanks in advance
