When wired up as it should be my heater blower does not work.
Replaced the resistor, still does not work.
There is power going into the switch but still doesn't work.
Fuse is ok.
Wired directly to a toggle switch it only works when on full blast.
Can anyone shed any light on what's wrong?
This is a N reg Xantia 1.9 TD

The fan switch is fed from the ignition switch, and it’s common for it to fail when the fan draws high current.There is power going into the switch but still doesn't work.
Without the motor current, it will have 12 Volts.
The toggle switch has another input feed, and the resistor is still fed from the ignition switch, causing loss of the lower speeds.Wired directly to a toggle switch it only works when on full blast.
At full blast, the resistor is bypassed.
Maybe try with a test lamp on the motor feed wire with the motor connected and set to spin.
