My AC was working OK but I knew it was most likely low on R134. About 3 weeks I took my XJ to the mechanic and he checked out the compressor and filled up the r134. The AC worked great after it was serviced. I used the AC a few times and it worked fine. Yesterday I turned on the AC and it blew out warm. The compressor seems to be working normally. What could be the problem?

 

I foundout today that I don't have any r134 left in my AC system. Is there a common place I should look first for a leak?

 

Condenser in front of radiator. Put some stop leak in or dye and look for leaks. I had same problem and replaced the condenser and its been working for 2 years (Fingers crossed...lol)...Tj

 

I would take it back to the guy that worked on it last.
clint

 

He's the one that foundout I had a leak. I did not have the time to leave vehicle with him tonight. He's going to look for the leak the next time I have a chance to bring it in. I just wanted to give him somewhere to start looking.

 

TrekkerJmm: Thanks, I'll have him start at the Condenser.

 

the top line that conects to condensor...right behind the nut.. the line likes to rust away...went junk yard hunting for one for mine.. looked at 20... 19 were rusty lol...

 

If it's the Condenser, is there a type that works better than others?

 

im workin on my ac now...i gotta get a new low pressure switch cause the compressor wont even kick on and im gonna recharge it and see if i got any leaks

 

I would also check the shredder valves for leaks. After they have been used they sometimes stick or the seals have just worn out.

 

there will be a greasy residue from where it leaks because it attracts road junk, grease, etc.

 

i think im gonna try that uv dye stuff...

 

All I can do is smile. I fix one thing and two more things go wrong. Eventually I'll have a brand new XJ. I love my XJ and I love not having a vehicle payment. But my XJ is nickel and diming me to death.
