Rover 400 1.6 Electrical Fault Mystery - BushMechanik
Recently bought a 98 Rover 400 1.6l for a run around but its beggining to drive me nuts. Heater control worked only at max (common prob 4 these) so thought to check the heating fan resistor which I discovered had been removed at some point. Am still to buy the resistor but now the electricals are playing tricks on me. Keeps blowing Fuse # 13 (Circuit : Engine cooling fan, wing mirrors and of cause, Internal Heating) Have looked everywhere for a short circuit but cant figure it out. Took it to my local and they couldn't too. Funny thing is sometimes blows fuse immediately after key on and sometimes after driving for a while.

Anybody has a clue whats going on? Thanks in advance!!

Could possibly be heater fan motor seizing up,also a common problem.Easy to check,fan motor access in pass footwell and 3 screws.Btw if you are to replace the heater fan resistor ,buy it from Honda for a Civic of the same year it is about £10 cheaper.!

As elekie&a/c doctor says common fault remove the connections to the fan motor and see if the fuse still blows.
