Air con hissing after regas
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?

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.
