Help! Have recently changed the heater fan in focus 1.6 Zetec - 02 reg as it had stopped working. Wouldn't work on anything other than setting 4 on the switch. The old fan was very stiff. Bought 2nd hand and a new resistor. Now the fan still won't work on setting 1 on the switch only 2 to 4. However, the aircon light comes on at switch setting 1 but none of the others. Not helpful when the fan doesn't work on #1.

Any advice welcom

Cheers

Stew
