It appears the shutter that blocks off the heater core is no opening fully. It is vacuum operated and mY HAVE A HOSE DISCONNECTED. The vacuum HOSE AND actuating control is accessible under the dash on the firewall passenger side. Good luck

How can I fix this my van only blows out cold air?


Check both hoses to heater core and see if they are both hot. If not, try back-flushing heater core. If the are both hot, you may have an air"blend" door not working due to bad actuator or vacuum leak. This is the door which changes hot the air flows into the heater core or not.

Why is heater not blowing hot air on 99 chevy blazer


if the fan blower is working then it must be the heater valve inline with the heater hoses. Or the selector on the dash has broken and is not connected at the back. You have tried everything else. You were correct in what you wrote above and have tried so far

there are two heater cores. autozone.com has a great turorial on how to replace. You could try to blow low pressure air through the heater core to clear out any gunk.

Heater blowing not so hot


How hot this gets is often regulated by the engines ability to properly heat up. This is controlled by the engine thermostat. Alot of times, people who have an overheating problem simply remove the thermostate without replacing it. This does not allow the engine to heat up properly (it actually is running too cold) thus the water coolant does not heat us. result, barely warm air through cabin heater.

A/c and heater


Is it leaking antefreeze?
The thermostat might be gone or needs a bigger thermostat
It could be a vaccum leak for the drivers side blowing cool air and the passenger side blowing warm air
Does it have dual air control switches one for drivers side and one for passengers side?
