Hi can anyone help? I've noticed as the weather is getting colder the heater in my wee van is blowing cold air. I've checked the water level, fitted a new thermostat, with no effect. I can get a slight heat if I set the temp at max and the blower at min, but nothing to speak of. The van temperature gauge does not overheat. no sign of any emulsification in the radiator water. I've tried squeezing the heater hose in case there is an air lock. Still wont work.
Please someone help before I freeze to death.

I assume the heater hoses are cool rather than hot.

My old Escort van had a little air vent in the heater hose to allow you to get rid of air locks. If yours doesn't have one, disconnect both hoses & flush through the heater matrix with a hosepipe. Refill the cooling system by parking the van on as steep an uphill slope as you can (or use ramps). This should keep the heater hoses full.
 
Is the linkage to the heater Matrix connected ?
Is the Matrix air locked ? bleed
are the shutters letting air into car open ?
squeezing pipes will not work.
