The blower motors are problematic in these from what I understand. Mine squeaks from time to time, it's located in the passenger wheel well and I don't think is a major pain to replace.

No blower.... AAC DTC
The blower speed controller is rather good. The opposite is true with the blower fan. They routinely go bad from tight shaft sleeve.
nice blower controller 👍
This networked speed controller looks well designed to have a chance to last a while.
Don't forget the cabin filter, it's the most overlooked part until thermofuse goes boom.
It is still time to spend 15mn to poke around for +12V. Test power does get to ballast them gets out to fan motor.
Not to mention basic GND paths are often compromised and rain leaks make their way to the speed ballast controller location.
Scan for fault codes, in particular AAC + related live data.
