One side diesel heater not working

[Evelynhl]

One side/vent of the diesel heater has stopped working this year. Any tips or tricks? The other side is fine, so we are not suffering...

If you mean the ones on the floor behind the seats then, it’s only the left one that is for heating.
The right hand side is fed from the heat exchanger for engine cooling and is controlled via the switch on the dash and (depending on year) the small control panel above the rear bench seat.

Hahaha. Thanks for clarifying! Then nothing is wrong
