991air con /heater fan

[foresterlad]

Off and on I have had problems with the heating system since last October. Firstly the water valve stuck closed, which is a known issue and was changed. Then the fan motor stopped working but could be coaxed into life using the full blast front screen de-mist switch, before it packed up totally just before Christmas. OPC carried out a software reset and lubricated the motor.I had expected a replacement. It was OK for a while, but leaving the car unused for two weeks recently and the problem has re-emerged on a "sometimes it works or not basis".
I would be interested if other owners have had a similar issue and how OPC/Porsche dealt with it.

The heater in my 991.1 GTS has worked off and on for the last couple of months. Went for a spin today, couldn’t feel my feet by the end. The OPC have had it twice (both time for nearly a week), replaced a change over valve (common fault) and the fan. It’s going in again in a couple of weeks (soonest they could get me a replacement car). If they don’t track down the root cause this time my patience will run out.
