I would start with the rear blower motor resistor, the resistor is what controls the speed of the fan, the resistor is located in the rear heater box near the blower, you will need to remove the right rear side panel to access the heater box. start with that

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

This is for front blower motor. The orange wire is voltage, hot all the time, fuse protected. The black wire is chassis ground, you can check both those wires with test lite. The top wire, control from hvac control module. That may be a pulse width modulated signal? This was for automatic hvac w/o roof.
bbbind.com has free wiring diagrams.

Sounds like a bad blend door actuator. That's the motor that diverts air between the heater core and AC

You might need to check does your fan still functioning or not. There is time when the heater fan lifetime will end. On the other hand, if you have to check your car lights or any electronic device whether it is functioning as usual or not. If there is some problem, that's means there is problem with your wiring.

The front blower motor is controlled by the blower resistor module.This is usually the problem with the front blower not working.I looked up the schecmatics and I don`t see separate fuses for the front and rear.But the fuse for the front blower is in the under hood fuse block.If this is good then The problem is probably the resistor module.It is next to the blower motor.The connector from the resistor connects to the blower motor.If you want to confirm this you can check for power and ground at the blower motor connector when you activating the blower switch on.This can be done with a test light.Make sure you have power going into the resistor module also.If you have power going in and no power at the blower motor then replace the resistor.Hope this helps.Good luck.

Here's what the system looks like. left rear panel
please rate as fixya if this solves your issue


Check fuse #7, 5 amp dash fuse panel
check fuse # 13, 30 amp in power dist. box under hood I think
check auxilaiary a/c relay in RPO Relay box (rear floor panel)
check fuse #23, 10 amp in dash fuse panel
