If you got heat when its running and almost nothing iddling the heater core inside the car has rectriction idle circulation not enough prestone pass thrue the radiator because of scale when our driving way more circulation more prestone go thrue ¸=more heat you need to flush the radiator inside the car normally i put a radiator flush leave it running longer then what they say go for a drive remove the heater core hose be carefull not to break the pipe use garden hose pass hose water pressure o n both side do it a few time each side flush all the prestone add new prestone you shoul have way more heat good luck p.s some shop might tell you change the heater core that perfect but very big money do it right its cheap and gonna work pierre

I have a '03 Dodge Grand Caravan Sport AWD that the heater only blow hot air when going down the road. Van has a new radiator and new thermostat. Sometimes the blower will not kick on for a few


If the problem is a lack of air flow from the vents, and you suspect the blower motor is not running at times, you would need to test the blower relay and blower motor for power and ground when it is not working.

2000 dodge grand caravan sport 3.3L flexonly blows cold air


You say you can hear the climate control work, but the blend door for the heater may not be moving. If both heater hoses are hot, I would suspect the blend door.

Heater slow to work


this sounds normal in very cold conditions! The air is never hot when you first start the car in any car, until the engine warms up, then the heater air will also warm. You could check your anti-freeze level for the first thing. If you don't have enough anti-freeze, it won't run through your heater to give you the proper heat

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.
