Hi,
I've got a 1986 8v 944 and the cooling system broke last week, the fan stuck itself on, so I'm pretty sure the Thermofan switch is bad. Only its stuck itself off now.. so i'm hoping the switch has just locked 'off' now, and not that i've burnt out the fan motor. The Mk-1 nostril suggests not as it doesnt stink of melted coils.
I can change this, but whilst rummaging around I noticed that I have just one cooling fan... All the literature and workshop manuals i've looked at suggest I should have two.. Can anyone shed any light on the change.. was it a cost down on later models??
Any help or other pointers of changing this switch would be great.
Cheers

Only aircon models have two fans.
You can test your one fan by shorting together the two fan wires with the ignition turned on.
To change the switch you will (ideally) need to borrow a 29mm A/F deep socket, you can do it without draining the system if you are fast getting the new switch in place, but do not overtighten the new switch as it is being srewed into a plastic radiator end tank. Remember to check the water level after the engine has run.
