defender heater

[Alex.Y]

in my defender the heating seems to have a mind of its own at the moment,

the fan control works OK, the direction works OK, either windscreen or feet,

the main problem being the temperature, sometimes it doesn't work at all sometimes it blows hot quickly and sometimes it takes ages to blow hot,

when it does blow hot it can then change to cold with no reason and nothing being touched.

does any one know where to start to get to the bottom of this?

Thermostat, would be a good place IMO
