Finally got around to getting the JeepAir aftermarket AC charged… just in time for Autumn!
I had a couple of small hiccups: the low-pressure line coming off the compressor was a smidge too long, so it became kinked when I installed it. I emailed JeepAir, sent them pics of the line, and they shipped me a new line setup with a shorter low-pressure line, at my door in 3 days. Crisis averted, and the system charged perfectly!
Everything was going great… except the HVAC was only blowing hot air!
after troubleshooting the compressor itself, the HVAC switches, and the vacuum lines/actuator, I found the problem: the blend door that is controlled by the temperature switch must not have seated properly when I put the heater core case back together, and it was jammed open, letting the hot air blow through the vents. I really didn’t want to go through the hassle of detaching the evaporator core lines and the heater core lines, taking the dash out, dealing with the 6 nuts in the engine compartment (again, fuck the Jeep engineers), and taking the whole heater core case out of the Jeep again, and I sure as hell didn’t want to pay someone hundreds of dollars to do it for me… So I jammed a flat head screwdriver up into the mechanism and started turning it back and forth. Then POP! The blend door was able to move freely, and I felt the sweet sweet victory in the form of ice cold AC!
