AMG GT Defrost Air Distribution Issue

Good shout! Where exactly is the blower motor resistor located? Is it a pain to get to, or relatively straightforward?

On mine, it was tucked up behind the glove box, accessible after removing a few trim panels. It's not terribly difficult, but a bit fiddly. But honestly, considering the symptoms, and that cost you mentioned, the defrost air distribution flap itself might really be faulty. At that price I would take it to the workshop.

Cheers! Ended up being a faulty connection as you suspected. Workshop sorted it. Thanks for pointing me in the right direction! Saved me from needlessly replacing the heater core or the entire climate control unit. Temperature regulation is back to normal!

Sounds familiar! I had a similar issue with my AMG, thought it was the heater core at first. Check the blower motor resistor and the climate control module connections. Sometimes a loose wire there can throw things off. Have you checked the HVAC unit fuses? Could be a simple fix before you chase the flap motor itself.
