I have a 2000 Dodge Minivan 3.3 with a hot AC! I'm no expert! I tried adding 134 with no luck. I let it run for an hour with the can hooked up and nothing. The gage read 25# low side. The compressor turns and clicks on and off when I push the button. Air coming from the vents is warm. Is there a common problem with these I could fix or am I due for a trip to the AC repair shop? :ball: - Bill
