Make sure your radiator is full of coolant, if it is low the heater core cant get enough hot coolant in it to keep the air warm. If that's not the poroblem it could be a problem with your air exchanger that switches from hot to cold which could be a vaccume line leak. But I bet you're just low on Coolant.
needs the water system back flushing out, heater being cold is its blocked up some time a few back flushes and forward flushes with a hose pipe should free up the dirt inside, same with the engine and radiator. there are meany videos on you tube to help you understand how to back flush you engie. but do the radiator and engine and heater separate so the muck does not go back into the engine.
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.
Replace the thermostat
check and or have the water pump check
open radiator cap start cold engine add coolant
step on gas a bit about 2000rpm add more coolant hold the peddle close radiator cap
either an air lock in system or thermostat faulty....you could remove faulty thermostat and warm air would get through eventually...or flush thru system and bleed
Thanks. How do I fix this & is it very expensive?
