wj 4.0 a/c problems
So it holds pressure but it just wont blow cold. It hisses when i accellerate and gets even warmer. Compressor seems to be working but the electric fan doesnt ever kick on. Could that be part of it? If so how come it wont? I straight wired it and the fan works. Relay is good and i replaced the temp sensor. Im stumped and its too dang hot in Texas.
That fan needs to be on when the AC is on to remove the heat from the AC. The air blows over the condensor to remove the heater from the air. If the fan isnt coming on then the pressure if building in the lines and the pressure cycle switch is tell the compressor to turn off, in return its blowing hot air.

The gage isnt jumping. But the fan never comes on. Ive had it idleing for 15 minutes and nothing. But the coolant temp is good. And the compressor comes on. So why isnt my elec fan coming on at all?
