981s heater fan won’t turn off. Any ideas?

[notax]

As above. A friend was driving my car, turned the heater fan off and the fan instead went to the maximum speed When the car was switched off the fan continued and the only way I could stop it was by pulling the fuse out. Any ideas? Thanks.

Heater fan peculiarities are often due to the resistor pack (which delivers lower fan speeds) burning out, leaving the car with only the max blower speed position still working. Usually a cheap fix by plugging in a new resistor pack. However, I've not encountered a situation where the fans won't switch off at all.

Aha! Here's a perfect link for you,

"Hi, I had this a few months ago on my '12 981B. All of a sudden the cabin fan would not stop blowing at full speed. I was given some great advice what to look for on Boxa.net, the likely culprit being the 'hedgehog' regulator - so named because of the heat sink with lots of rods/prongs sticking out.

I ordered the part from D911 (I think), something like:-

Fitting it was an easy DIY, from within the passenger footwell. I can dig out the thread from Boxa.net if you need it. Good luck."
