Heater blower still not working

[Rizzo]

Following a battery change, I lost the heater fan blower completely doesn’t work on any setting. Having browsed the forum I’ve changed the fuse, relay and today the resister and still nothing. Anything else I should be checking before I change the motor?

I would disconnect the wiring from the blower motor and use a power probe to give it a live feed to see if it will run. A basic power probe is fairly inexpensive these days. When I got mine from Snap-On Tools many years ago they were around £100.
