Heater Fan Not Spinning
Best Answer sonikk4 , 23 September 2017 - 06:24 PM
You will need a Fluke / multimeter to see if you have power to the switch. As for the earth this will come off the motor itself. Its possible it broken off or damaged. On my Clubby, the earth lead was trapped between the heater body and lower dash rail. Also luckily for me the power lead insulation has also been damaged but had no shorted against anything.

I have checked the switch works and it's not the fuse as my wipers still work, all the cables look in good condition so I'm a little stumped
Any ideas appreciated...

Two leads coming out of the heater motor, one goes to the switch (green/black IIRC) and the black one goes to ground (or earth as you guys say it) check to see if you have power to the switch, and coming out of the switch first, if you do and you're certain the ground is good you may have to drop the heater assy to see if something is stopping the blade from turning or if the motor is simply bad.
Lots of people have found mouse nests and other things in their heaters keeping the fan from working.....

No power to the switch tells you where your problem is, just follow the wire back to either the fuse box or the inline fuse, whichever it has.......
