Need Ac Help 86 dodge ram 50
ok so i just bought this truck and it seems to me that everything was installed from factory.
The issues i have are that
there is no ac on/off switch on the hvac controls, no big deal ill add a toggle switch.
But none of the wiring is hooked up
i believe that the pressure switch is on the evap instead of the compressor, there is a black lead coming off the ac clutch, goes no where, black lead off of the evap that goes no where but i believe should be hooked up to the ac clutch??
one plug off of the evap, a two wire (green), which is the pressure switch? not connected to anything.
I know that the on off switch gets tapd into the yellow wires off the thermister control.
I guess what im saying is that i have an idea but i am not sure.
If anyone has a diagram of the ac unit, or ant help that would be great.
ps i also dont see any freon in the sight glass on the evap, how can i jump the pressure switch to bypass it, just to see if everything else works. if anyone has any links to retro fit to r134a that would be great too.
thanks guys:))
