Rear Heater only blows cold air

[koiman]

Hi Guys

Just bought myself my first bongo camper and loving it. a 53 plate 2l auto petrol with side conversion.

Except of course the mpg!! coming from a diesel car that get 70+ mpg its gong to take some getting used too.

Okay. Question for you all and hope you can help me resolve.

The front heater works brilliant however when I switch to rear all I get is cold air blowing out. I have found the rear controller and set this to max but sadly it made no difference. I have checked the fuses and all are good.

Can anyone point me in the right direction or give me some things I can check to see if I can manage to fix it.

Many thanks

The heating comes from the engine coolant, so provided the vanes are selecting the heating matrix to be in the path, the chances are that the coolant flow is blocked or has been bypassed externally as its common to suffer coolant leaks which are never a good idea in a pressurised system! I would check first of all underneath drivers side and confirm that the coolant pipes are still in place and haven't been bypassed.
