Hello all.
Just had my air con regassed. It worked for a few weeks but now there's a loud hissing sound that sounds like it's coming from the passenger side. The air con is also pumping out warm air.
Any ideas?

I have a cl55 2002

You have a leak. Going to have to fix it and refill. Turn off your ac in the mean time.

Thanks for the reply. Is it a DIY job to find the leak?

No a leak is a mechanical problem, the car won't be able to diag where it is. Most a/c system leaks are either the evaporator, or object damage on the compressor. Generally speaking you will see oil residue from wherever it's leaking. If you can't find it, it's probably in the evaporator core inside the dash. GL, I hate a/c work.
