Heater not hot in sprinter van

[Donka]

Hi would anyone have a scooby doo why my blower in my sprinter van never gets warm. It never gets past just above cold. Just warm enough to clear the screen after a while. I seem to remember some garage messed with an overheating problem a few years ago cheers Donka.

Check the pipes from the heater matrix see how hot they are. Might find that something is blocking the filter or the matrix needs flushed.

Recently had to get heater motor replaced and was quoted ?230 for parts and labour. After bit of research found it might be the brushes in motor worn. So after taking one out just to see how easy it was i just replaced it until i got a new set, after this blower starts working again. It seems to blow reasonably fast listening to it but not much air flow or heat seems to come out of vents. I've noticed a trap type door above motor fan does this dictate the heat to the cabin as i'm not sure it's working, don't get that slamming feeling like it's closing on any of the buttons. May try it manually tomorrow. My hoses feel soft to grip and it feels like they are chrystalised on the inner tube. Hope someone can help. PS what about the garage asking ?230 for nowt, cheers.

The seem to feel soft to grip and chrystalised inside if you understand, how should they feel thanks for you reply.

could be your thermostat is jammed open forcing the water round the radiator thus cooling it constantly.

could be an airlock in system, may need bleeding.

What he said ^^^
Also check your water level (antifreeze)?

see if your water pump is ok, then if you think that termostat is jammed drill som holes in him, also you can pull ot fan motor from cabin and put your hand inside to try to feel if it is wet, and if it is change your cabin heat exchanger...I call it cabin radiator hahahah. he might cracked and leak.....

Check to see if the actuator that change the air flow from the evaporator (cold) to the heater core (hot) is working. It might be stuck or does it have a heater shutoff valve, check to see if your heater core is getting hot.
Hope this helps!!!!

if it had an overheating problem in the past i would imagine the stat has been removed,if there is a stat in it drilling holes will make it run cooler!,check the pipes to the heater rad are getting hot,if there not then make sure it has a stat fitted and that your coolant level is ok,if they are getting hot check the control flaps in the heater unit are working,also check the pollen fillter isnt blocked if fitted,if all that checks out ok try back flushing the heater matrix,hope this helps,paul.

you say you have no heat ? how is the air flow through the vents ? there is a cabin air filter below the wiper module in the engine bay behind the insulation . I have seen the plug up bad causing no air flow & no heat .
