Hi all,
Had a very frustrating day. My fan interior has packed up, which in winter with rain isn't nice - I'm having to drive around with the windows down to stop my windows fogging up. If anyone could suggest what is wrong, I'd be grateful. Here is what I've done so far:

Checked fuses - all fine
Checked power - 12V registered through the input wire
Checked motor direct to car battery - Works fine
Tried new motor - Not surprisingly, didn't work


The fan doesn't switch on at all (no matter the speed setting), so I imagine it isn't the resistor. The guy from the Fiat garage selling the parts suggested new wiring, but surely that isn't the problem if I'm getting a power read out?

Any ideas before I have to pay a mechanic to go through all the wiring and charge me a fortune

Thanks

check the plug on the back of your heater control is secure too just because you are getting 12 v dont rule out a bad/ melted/ loose contact. even with a high level of resistance you will still get 12v showing on a multimeter
