My resistor gave up the ghost - and I wanted the fan going without dismantling half the cabin to get to the resistor. I had a good look to see if I could get to it somehow but gave up.
I've had a PWM controller handy and added a little knob for fan speed into a blank panel plug just below the regular fan switch. The regular switch still changes from recirculating to fresh air and air-con on and off. The new knob sets the speed steplessly. No more worries about resistor....
Ok so this is an ancient post but my resistor has just packed in and this looks like a much better option than taking the dash out...
I've found a similar controller on ebayhttps://www.ebay.co.uk/itm/226437049060 ... BM6vKz8_Jk
My question is how does one go about connecting it? I'm reasonably handy but a bit hazy on electrical issues so any advice would be much appreciated.
