Anybody have any experience with the HVAC ECM?
None of the main head functions are working.
A/C, blower fan, front defog, rear defog, seat heaters, etc.
I’ve checked all the fuses and they’re good.
Is it possible the whole HVAC ECM could have failed?
If so, what’s the best way to diagnose/replace?

Need a scanner and check for codes
