Heater dose not get hot changed thermostat and heat resistor flushed core is there a fuse or sensor

hi tammy
it could be an air lock stopping the water from circulating properly i seem to recall this problem on the older VW Derby and audi 50 (same engine) there is a small bleed screw at the highest point on the cooling system that allows you to bleed this air out youll find its location in the manual

another thing to try is put a flushing agent through the system incase there are any blockages in the radiator itself

hope this helps

Is the blower motor working? If not that is what it is. If it is working then check heater coil out, Could be bad heater coil.

Good place to start is a cooling system flush and thermostat replaced.

Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

Sounds like you have air trapped in the heater core when you flushed the heater core. loosen the upper most heater core hose and run the engine untill coolant seeps out. Wait until the coolant has reached running temperature.
