have been a guest of the nhs for 4 weeks and on first driving my 991.1 all was ok - except heater and brake discs (latter sorted themselves after a short drive as usual). however heater and fan won't do anything at all. controls show fine all buttons light up fan controls allow adjustment of fan speed etc - but diddly squat happening at the air vents - no fan buz at all and no cold air and no hot air.
am I missing something obvious or is it off to OPC for fettling again ?
thanks
