Go to start, do not collect £200 for passing GO...In other words ALL the required information is in this topic if you start from the top of page one.

1) For your problem, no fan at all, the most common fault is the switch itself.

2) Blower motors commonly fail because bearings get stiff because of water runs under an incorrectly fitted seal between scuttle cover and windscreen. That comes through the pollen filter. Motors can often be recovered using WD40 on the bearings after removal from the passenger footwell.

3) When the blower motor gets stiff, not enough air passes over the resistor pack used to slow it down, and a thermal fuse welded in the pack blows (~200 deg). Then the fan only runs on max speed - 4. Replace resistor pack or the thermal fuse with one from Maplin soldered in place.
