AC stopped working, then the fan stopped blowing. All fuses checked, no codes showing. Any suggestions?
Bad BCM can cause that.

I don’t doubt that a bad BCM can cause this problem, as well as other problems, but… I have never had a BCM failure on any of my cars.
How common is BCM failure?
I’ve replace six or seven over the years.
And the first one I replaced was on Vibe for no AC/blower fan.

Maybe the A/C amplifier module is another possibility? Pretty expensive guess I would imagine without doing a thorough diagnosis.
Personally, I don’t like to dig into electrical things without perusing a decent schematic first and sometimes I don’t even fully trust those as I have found errors even in factory publications. Rare I admit but they do happen.
