Hello,

I'm not getting power leaving the fuse box from fuse 19.
I'm not getting power from fuse 19 therefore my electric fan setup isn't running.

The fan switches on straight away when I give 12v to the pin 1 on the fan temperature switch, so I know the fan wiring is all working and done properly (as per the standard aux fan wiring from factory).

On fuse 19 I had two green/purple wires but just added on my +12v cable which goes to pin 1 on the temperature switch.

Wanted to ask if I've missed something.
The car doesn't have an engine in at the moment, and most of the interior and switches have been removed as I'm doing some work on the car; not sure if all this would be the reason I'm not getting power leaving fuse 19?

Also, the main 12v fuse box +ve cable is connected to the battery.

Thank you.

19 is for wing mirrors, not fan.

Fuse 19 is for the door mirrors (haven't seen wing mirrors since the early '70s), fuse 20 is for the heater fan.
Neither will receive power in a car in which the engine is missing, since both are supplied by unloader relays which will not work unless the starter motor is present and wired.
Thermoswitch for an electric radiator fan should connect to fuse 19.

Ok makes sense now. Had a feeling it would be something like that.

Yes the fuse 19 goes to pin 1 on my fan switch in the rad.

Thank you!
