2006 Buick LaCrosse.
Interior Dual Zone AC/Heating control is the electronic Automatic system.
Anyway....my Father was driving the car and he told me it overheated and caused the AC shutoff to activate. After putting my computer on it, I discovered that there was no fault code stored in the ECM so I don't believe it overheated and shut off the AC. I believe his AC simply shut off.
BUT....now the interior fan is not blowing at all. It's a dual zone system so I assume it has two fans for inside HVAC. Neither fan is coming on. I have checked the following fuses and relays:
Underhood fuses:
F29 - Fan 1
F32 - Fan 2
Relays:
42 - Fan 1
43- Fan 3
46 - Fan 2
The HVAC control center powers up and seems to work fine but just no air blowing from either fan. Do you guys think it's a bad HVAC control board (the inside display that controls your climate)? Any other idea? Anyone ever experienced this issue?
Thanks
