Disco 3 (LR3) No Hot Air

Hi Need some help regarding getting no hot air from the heater, thought it might be the thermostat but gauge showing the the engine is running at the right temp. Any one else had this ever happen to them?

Have you checked fuses ?

All the heater controls and fans seem to be working fine, Are there separate fuses for the heater?

It's probably a servo motor, most likely the blender motor. Best run a diagnostic on the HVAC system, to see what flags up.

Search google, you can run a hvac self test yourself.
Have you actually felt the coolant pipes where they enter the cbain?
I would still replace the stat as a first/cheapish thing to do.

Is the fbh running?
Like most land rover diesles they are pretty cool running.
