As my finger fell asleep today pushing the button to get the windows down, I was thinking how nice it would be to have an express down feature like the new cars have. Anyone done this and what was needed to make te change over? I guess I could pull out a newer GM service manual and compare wiring diagrams with a car with expresss down, but I'm too lazy. Then again, I may do it just for something to do. Thanks.
