I believe the heater relay is on the side of the heater box, could be the on/off/speed control being faulty.

Ok some dis-information may be, I was looking at my parts catalogue and heater is where it's shown but in Haynes it's called "front blower motor relay" is located "behind passenger side facia"

Hope that is correct and helps.

If youv'e dismantled everything can you not test for 12V at the blower motor terminals? If you have voltage, it's not your relay at fault.

Got a '92 Disco V8 myself, and my heater blower fan stops working in winter. But in summer it is fine again. My guess is that there is moisture in the switch. I'll wait for the summer and 'll give it a good WD40 treatment.
