What's the problem with the heater blower? Does it only work on one
speed. Does it not work at all?

Any other electrical problems?

Use a test light to check each fuse.

Start with fuse #11 (30amp). In case Audi Diagrams aren't easy to follow.

The blower ground is controlled by J126 (located in the engine
bay HVAC air duct).

Forgot to mention that with a scan tool such as VCDS, you can perform output tests of
components such as the blower motor.
