I've changed my car (Brazilian GM Classic) oil and after the change the A/C stoped working.
I've asked for the car dealearship I've changed the oil to check it up.
The diagnostic was that the A/C compressor was damaged, the solution was to change it. They explained to me that this damage may happened in some flood I've passed by. The explanation was that with the A/C turned on while passing through the flood, the water may be pulled inside and damaged it.
Does this make any sense? Or its just cheap talk?
