Today I realised my heater fan has packed up. Doesn't work on any setting. Looks like the fuse is fine. Guessing I need to replace the resistor pack?
I had the same problem. Mine was a loose connection on the earth cable that connects to the negative battery terminal.
Okay mate cheers for that. I'll have a good look over it later today. Seems funny it's just packed up. I thought when resistor packs went it still works on full.
On inspection my fan motor had completely seized. Dealer replaced that and now needs the resistor replacing too!
Sorted this in the end. The connection which goes to the fan motor had corroded. Cleaned it up and works fine.
