Hello, a few weeks ago a horrible grinding noise was heard from behind my dash, since then the speed control switch only works on full.
I have repalced the heater blower fan unit (behind the glovebox) but it still only works on max speed.
Any ideas what else it could be, the switch etc, or is there something else (Relay?).
How do I change it/the switch?
Thanks

Usual culprit for a fan only working on the fastest setting is a failed resistor pack.

Thanks, do you know where this is and is it replaceable?
