I’ve been battling this issue for about 6 months now. 3 different shops have failed to diagnose this issue.

basically, my HVAC recirculating button is not working when I press on the button. (I know when it works - I can hear something when the air is circulating for the inside). Two shops couldn’t figure it out, one shop swapped the whole control panel out, but the problem still exists.

I am at a loss on what to do at this point. Is this more of a fuse issue?

 

About the only thing left is the door.
