Hi All,
I have a 1996 +4 and the heater fuse keeps blowing. I have put in a 30 amp fuse, it works for a period then it will blow at random. I have checked the wiring all looks ok.

The fan also only works on position 2 so no function on position 1.

Any ideas what the issue could be?

Switch faulty or sticky heater motor?

Many thanks
Will
