Sorry Not an old Mopar.... but a newer one.
This is a 2010 Dodge Avenger (RT 3.5l)
This spring my wife noted that the AC in her car wasn't working. I checked the system and found it was low on charge (just enough to not override the pressure switch). I recharged it and all was well. 3 weeks later it was low again just like before. I decided to recharge with some dye this time in hopes of finding a leak.
2 weeks later (yesterday) there was little to no refrigerant left. I borrowed an AC sniffer/ UV light from a friend and found that the connections at the condenser were leaking. I replaced the seals last night, pulled a vacuum on the system for about 40 minutes (pulled down to 28inches). I let it sit another 30 minutes with the valves closed and the pump off and saw that the gauge had not moved. I went ahead and charged the system.
Today, my wife gets in the car and the AC won't work. Haven't got to check yet, but I am assuming its low.
What am I missing? With the vacuum test turning out as good as it did I can't understand how it would leak down so quickly.
