heater switch first stage swathes ground with resister - stage two or flat out bypasses resister to the motor

check that you good ground the switch

black wire with black spade on the end and male spade lug on the switch lever



Is there a 60 amp fuse under the drivers seat for the fan? Could that be the problem?

OK still no blower fan!

Is there a way of putting power to the fan via the connections in the engine bay to see if it will spin up?

Cheers

Hi Dunk,

I wanted to do the same thing a few years ago so I bought a Sealey PP1 Auto Probe. It’s ideal for powering up 12v components.

Hope that helps

Fred

at the plug purple and green wire needs to have 12 volts + to battery - with the ign switched to pos ii

Green and slate gray wire and green and yellow are switched to ground i.e. battery - this cared out with heater speed control

a Digital Multimeter so you can read dc voltage and Continuity and Resistance and Test wiring good tool
