Auto Air Conditioning (AC) Issues
 
I have the Auto Climate Control and today when I started it up I have no air blowing out of any vents. The knobs and interior a/c light and re circulation lights do not illuminate as they have no power. The compressor will randomly kick on for 6-8 seconds but no air comes out.

Is there a blower relay or fuse somewhere. I believe I have checked the ones inside and under the hood. What tests with a meter can I run to diagnose the issue? I'm in Florida and no a/c will not last long lol.

Thanks

Have you tried adding a can of refrigerant?

did you resolve this issue? I have the same problem, and have changed the blower motor and blower control module but still no air blowing. Compressor works good. I have rising signal wire voltage when turning the fan speed up. Only problem I've seen is 3.4 volts going to blower motor from the Blower CM but it is a brand new AC Delco module just bought today. Anyone out there know anything else to try??

Yes I did, it actually ended up being the interior dash controls. I changed them out with a junkyard controller and it worked perfectly, hope this helps resolve your issue.
