My independent guy has replaced the wiring harness that was hacked with the stock unit and has also replaced the climate control unit. He says he's got the heat, fan, defrost, working but for some reason the AC compressor will not turn on. He says there are alot of safety related switches related to the compressor that will turn the compressor off if for example the v-belt starts to slip, or the transmission temperature gets too hot.
I know the compressor works as it was working and the clutch was just replaced.


Anybody have any idea why the compressor still might not turn on?

thanks
