SOURCE: 2002 caravan, heater problems

That was a common complaint a few years back, due to the fact that the heater core is a little too much higher than the engine, which requires that extra push it gets when engine RPM's increase. One thing I did do on my Caravan was remove my hoses to the heater core, and use a small external pump with hoses to circulate C.L.R. through my core for a while, then let it sit with CLR in the core overnight.Next day I circulated it through again, both ways by reversing hoses, and then re-attached hoses, bled air out of system, and notice quite an improvement in heat at idle. Once cleaned out, the heater core allowed coolant flow through it better at idle. If your stumped by explanation, take it to an automotive shop, or a Rad shop, and get a quote on flushing that core out for you. I recommend the CLR, but it might be too time consuming for you , but a flush will probably show some noticeable improvement.

SOURCE: 1998 Dodge Durango blows cold air when using heater

The problem that has caused this cold air only issue is the Air Temerture Control Blend Door Actuator Motor, this motor is on the ouside of the air duct about center of the dash, in order to access and replace it u must remove the entire dash assembly. this is about a 12-15 hour job.

ok, missed the part about the rear ac working, the part that causes this is called the air temperature control blend door actuator motor, it is an electric motor driven gear drive that moves the plastic door inside the air ducking to mix or shut off the hot or cold air from the ac evaporator core or the heater core, you will need to replace it.

No rear heat


The rear vent system has a separate heater core/blower system. heater core could be plugged up or the coolant lines going to rear heater core are plugged. could also be low coolant/faulty water pump not producing enough pressure, or air in the cooling system which will need to be bled if so.
