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: i have a 2000 dodge caravan, no heat

Sounds like the air "blend" door might be inoperable. This door opens and closes a specified amount to regulate the amount of either cooled or heated air, as requested by the climate control unit. If the door is continually in the position which is bypassing the heater core (cold setting), the air will not get warm regardless of the condition/operation of the heater core. I'd suggest having this component checked.

2010 dodge caravan ac gets cold then hot


2 things come to mind the first is are you stepping on the gas to accelerate when it happens this will be caused by a vacuum leak somewhere in the emissions or under the dash/ second are you standing still and you feel the air get hot if this is the case your cooling system is running hot and the heat is transferring to your a/c condenser and making it hot reducing the cooling effect of the Freon because it is getting hot itself

2001 Dodge Caravan heater blows cold air when stopped


Have you checked the coolant level? What you describe is exactly what happens if the coolant level is low. When stopped at idle, hot coolant is not circulating through the heater core, so no heat. As the engine increases in rpm's when you pull away from the light, the water pump is spinning quicker, and some coolant is making it to the heater core. So check the level, and if it is low, keep an eye on it to see if it drops again. That of course indicates a leak somewhere. Get it fixed, as overheating the engine leads to costly repairs and worse case a new engine. Let me know how you make out with this.

There is a recall that has something to do with the air/heat system in 2005 Dodge Grand caravans. Recall F01. Here is a link. I had mine done two weeks ago, cost me nothing. My air conditioner was overheating.

After car heats up (slow to heat) it stil blows cold until moving


You have a circulation problem, heater core may have restriction that why heat only comes when you drive ,also you may have a thermostat that stuck in the open position. Good Luck
