Any advice here on this? _______________________________________ There is a over temperature protection in the resistor pack - a temperature fuse. Once it blows the fan works only on high speed ("4") that supplies power to the blower motor directly by-passing any resistors. It's the diode looking thingee in the pack (the rest are coil resistors) easy to see. Replace the temperature fuse with similar fuse rated to something like 100-110 degrees celsius (Original is 109 deg Celsius, but more troublesome to find). Replacement part of 100-110 degrees can be found virtually almost in any electronics shop - cost,,, maybe 0.5-1 Euro... One you get new fuse use innovative way to CRIMP it to the wires,,, do not weld! Welding don't probably stand vibration, heat and coldness for long... Resistor pack can be accessed without removal of the motor. Follow the leads and find a small "oval" shaped cover that is held in position by clips in the end of the blower housing. Hope this helps you 60 sterling pain ;-) SuoTimo BTW,,, this might increase you pain,,, if the bearings of the motor are getting bad the motor drags in start and causes overheating in the speed controller thus blowing the thermal fuse... But try first to replace the thermal fuse,,, they also tend to get bad by time.
