Hi all,
I'm hoping someone can help me out here. I'm trying to fix up a much neglected 1974 F10 and I'm having trouble with the heater blower. Does anyone know where the fuse is located? I realise that the blower motor may be stuffed but as it is almost impossible to remove I am trying to discount all possibilities.
Thanks,
Scott.
In the main fusebox, from
In the main fusebox, from memory there are only 6 fuses.
However:
These have a fixed supply and it is controlled by a variable resistor mounted on top of the heater motor itself and these resistors blow so no power gets to the motor. Bypass the resistor with a short bridge wire and it should work the blower and confirm its the resistor which is blown.
Had a similar problem on my F20 (same system) and this was easily overcome.
If you have the two speed blower then remove the resistor totally, wire straight to the motor; take a 10 ohm ceramic power resistor (few pence from electronics shops) and solder this directly to position 1 of the heater control switch and this will give the resistance for slow speed operation.
