Hi Im David, does the fan work on all other speeds? i know you said the ac only works on low speed, but what happens when you change fan speeds?

Has a new control in dash
Expert:  david craig replied 10 months ago.

oh ok....hmmmm the speed of the blower motor fan should have nothing to do with the compressor operation. all the fan is doing is blower a higher volume of air.

What control a c clutch
Expert:  david craig replied 10 months ago.

when you select ac on the control panel, its sends a signal to the ac compressor clutch relay. the relay closes and sends that signal to the connectotr on the compressor that energizes the coils inside and pulls the clutch in to engage it.
