I took my caddy in cause a/c had quit working. Compressor was noisy and had a burnt bearing smell. Clearly there was a problem with compressor and it was changed. Morning after I took car home I heard a soft hiss under the dash and then a soft "pop" and a cloud of freon(?) Come up from the right side of the engine (hood was open to jump car). Took car back and was told I had an evaporator leak.
Called another mechanic who said system should've been leak tested before compressor work was done. Said he always does this as compressor went out for a reason and no sense replacing compressor if there's a bigger problem, etc.
I told my mechanic this and he said he couldn't leak test system with shot compressor. I think he could've - but I don't know.
Short/long - 2 quesitons:
(1) Is it standard practive to leak test a/c systems before doing repairs, and
(2) Can you leak test an a/c system with a shot compressor?
have the same problem?
