2010 Toyota RAV4 -HVAC trouble

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.
