Hello helpers!

I have 2 astra mk3's, one is a merit, one is an LS, my grandad has a merit and we used to have an artic in the family (i was too young to drive then!) and with all of these cars, the same problem has come up....the radiator fan only works on full power (4)! nothing on 1, 2, or 3. i wondered whether it was just the switch, so i went up the local scrappy, and took a switch out of one of the other astras, and that one now doesnt work at all! so i was wondering if anyone else had the same problem, and if so, did you manage to fix it? or does anyone know what is going wrong here?

thanks in advance guys.

Do you mean the heater control only works on 4?. Thats usually the resistor in the motor and is fairly easily accessible behind the bulkhead where the pollen filter goes underneath the wiper mechanism.
