the fan works ok for a while but when car is switched off,filling with petrol,going shopping etc,it will not work for a while but will come on eventually,then is ok,the fan speed alters sometimes,it sounds like a loose connection or broken wires.im guessing in the fan area thanks craig
99 e36 323i heater fan problem.i have looked at this fault,after checking hedgehog and other connections,i looked at the fan motor itself the two wires going to the motor had dirty connections,when touched the motor would run or cut out .i removed cable tie which held wires to motor then removed each terminal,cleaned and closed the gap on terminals,then refitted with new cable tie.it is now working perfectly without fault and without cost.
