As the title implies, my A/C has suddenly stopped working; I have already checked the fuse and relay inside the UBEC, and they looked fine. I can't check the refrigerant level, because I don't own a set of R134A gauges. The only things I have ever done to my HVAC system is install the Cabin Air Filter, Clean the Condenser, and replace the heater hose that blew. And before you ask, I used a commercial grade coil cleaner (that is safe on aluminum) to clean my condenser, and used LOW PRESSURE water to rinse it. Any help is appreciated.
