Thanks, I will pull everything apart and clean it all. I don't think it's the switch as I tried wiring direct from the motor side of the switch to the high lead and had no joy.

Hi all, new here so please be gentle! I have a Wolf 90, no issues with the heater till today when a baffling thing happened. I was driving home with the heater on full speed and got stopped in traffic. I turned the fan off with the speed lever after a bit as the engine had started to cool (first time I have turned it down, normally it is on 2) and then when I went to turn it back on nothing happened. I got home and took the wing vent off, fan spins freely so that is OK. When I set the speed to 1 or 2 with the switch and then spin the fan by hand the motor carries on OK but if I turn it off by the switch or by turning the ignition off it will not restart on it's own. If I spin it by hand it will restart as before. I am pretty confused by this, any ideas what it could be? Thanks in advance.
