Heater / Blower

[bigdog23]

Happy New Year to all forum users.
97 1.8T A4, the heater blower has suddenly started faulting, I will describe as best I can. The screen still displays the temperature and the power level of the blower still shows up, and all the +/- controls work, the issue is either no air coming through OR a knocking noise starts with a trickle of air, 1 person says electrical get it on a diagnostic, another says bushes on motor, any advice?
Thanks

More than likely brushes in the motor mate you can take brushe out and stretch the springs so they make contact again or just buy new bushes on eBay for about a fiver they are easy to change, fan is behind glove box, remove glovebox five screws I think and take motor out.

worse case is you need a new fan and brushes
