Q: A/C blows only hot air

asked by on August 08, 2016

My minivan’s A/C only blows hot air. I added freon, but the clutch never engaged. Then I pulled the connector from the pressure switch and shorted it. I started the car and the A/C, but the clutch would not engage. Then I checked the relay and also the fuses. Both of those were good. The low side revealed 100psi on the car gauge. What is your diagnosis and what will solve this? Thanks.
