My Ford Focus 2002 heater resistor pack only lasts a couple of weeks then blows again so i was thinking of adding a inline fuse on the power cable running to the resistor pack. Does anyone know what current used to run the resistor packis. i.e if it runs at 25Amps i will add a 30Amp inline fuse. Also does anyone have a ford focus wiring schematic

have you tried lubricating the motor bearings? if the motor is a bit stiff or if something is jamming it, it will overload the resistor pack & the switch & anything else associated with that circuit. as for the fuse, it should already have one in the fuse box, check with your handbook to see if it has the correct one fitted.
