Why would the AC stop blowing air altogether?

Asked by bclowery Sep 18, 2010 at 08:46 PM about the 2004 Mazda MAZDA6 4 Dr s Sedan

Question type: Maintenance & Repair

4cyc and have 101000 miles. I started to have problems with the AC not blowing
any air. At one point it would work for a few weeks then stop. Then the other day i
was driving and the air was working fine and just completely quit working. The
compressor will kick on but no air will come out of the vents. Could you please
help me in determining what could be wrong?

Thanks

It is a problem with the circuit your AC blower is in. First check the fuse, what wiring you can access, and the switch. If it's not any of those, I would suspect the AC blower relay, usually located in the engine compartment. I'll post wiring diagrams if I can find them to make it easier to find what wires and components to check. If you can't read wiring diagrams then have your mechanic look at it after you check the fuse and switch.
