My 87 GN has the regular, mechanical climate control(the switch and levers that you have to slide by hand). I was wondering if the touch-pad electronic control(for heater, A/C, vent) would work???? Can I just swap them out? Or do they have completely different was of being hooked up from the back??? My friend is selling one, and if it would work in my car, I might try it. I'm just asking before I go thru the hassle of taking mine out, installing his, and having it NOT work right......all in 20* COLD!
