Recently my Honda Civic 2006 AC hasn’t been producing cold air, so I took it to a shop. They topped off the Freon for $80; that didn’t help. They then found the relay to be bad and tested a working relay, but then found a bad wire to the air compressor. In the end, they quoted $220 to replace the relay and repair the wiring. They said it is a several hour job.
My first question is can they actually tell the relay is bad without the wiring working? Secondly, does all this sound “right”?
