Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Replacing a bad hose would not cause the compressor to fail. If the compressor is actually bad it was most likely that was the problem all along, unfortunately if the hose was leaking there is no way they would have been able to read the pressure with out fixing the hose and recharging the system. Have they gave you a systems pressure reading with the new hose installed?
I would have to agree, adding Freon and dye should have told them if the compressor was bad before they replaced the hose and if they went ahead and replaced the hose then they should have known the compressor was okay, it sounds like they do not know what they are doing and are just guessing. Unfortunately getting them to cover this my be a battle. I think what you need to do is get the car out of there and seek a second opinion.
