My 2005 Jeep Wrangler has a slow leak somewhere in the A/C system. I have owned it since new, and the A/C went down a couple of years ago. I can charge it up with a small R134a can, but it leaks back down within a few days. To clarify, it doesn't leak completely out, just down to a low pressure and seems to stabilize. I have it serviced last Fall, and the mechanic said he had to replace the Schrader valves in the service ports, but he had to use some used valves (oh well). Obviously this summer it was down again, and a friend at work who is a mechanic for our company helped me replace those again, with new ones. He pulled a vacuum on the system and it held; he charged it up, but within a week it was back to its non-functioning self. He also had a "sniffer", but couldn't find any evidence of leaks anywhere. Any ideas? Am I going to have to disassemble the system and replace all the o-rings?
The other thing is sometimes I get a loud thump from behind the glove box within a few seconds after I turn on the A/C, from the vent position. I don't think it's a blend door, because doesn't air flow over the evaporator core even with A/C turned off?
