BWM heater problems--display and switches working but no fan

Does the switch works in other modes ( ac, def ) If not , ck power & ground at the fan itself in all modes., If OK R/R the fan. If the fan only loses power or ground in heater mode look toward the wiring------switch control. Good Luck.

Both "blower" fuses are fed by the ignition switch. If there is no power to those fuses than the switch is the likely problem.

There is a resistor pack that controls the fan speed switches. Not sure about the 2000 Disco but on Range rovers of that era it is under the cover below the decker panel.- namely at the rear of the bonnet. Check that it actually is there, then get back to me and I'll post details of how to replace it

Most of the time when a heater blower quits working it is the blower switch that fails rather than the motor. Blower switch can be accessed in the dash panel.

no your problem is you resistor its broken so you need to get a new one then your fan should work perfectly good lick hope i gave you a good hint.

Maybe check for a fuse that is blown, or maybe the heater control has burnt out.
Is it a digital display one or is it just a simple fan switch?

next to the fan motor there should be a connector that has three or four wires that attached to the blower resistor. it should have two screws holding it to heater case, just pull it out and replace.

If the heater only works on the high setting, your problem is the heater fan resistor, not the relay.

check fuses,could be fan switch or at worst fan motor,need to get it looked at,

Are you sure it isn't in the switch itself? I believe the fan is under the hook on this car but I don't have my books here to know for sure. If you disconnect the plug to your heater motor and insert a test light inside of the plug that goes to the motor you could see if you have power there with the ignition switch on and heater blower fan switch on. The motor is about $30. to $50. but I definitely would test the motor before buying another one.
