  • Heater blower fault

    I only have the fan working on speed 4, 1-3 gives no fan at all! I've been told I'll need to swap a transistor that controls the fan speed? Any idea where this is located? Or part numbers etc?

      quick fix, cheap part, just ordered one myself. It's located underneath the windshield cowl, you have to remove the wipers.

            I Have a couple of the H pins that push in,along with some Butyl sticky stuff,to use when putting the cowl back,happy to send to you (for Free) if required just pm me.

            I am sure that i did not have to remove the blower unit just pulled the part out replacement was easy too ! this was on advice from the Parts chap at BMW,
