My Caravan got a leak from the "Y" fitting, Behind the thermostat 1 hose splits to 2 hoses and this part is plastic!!!! it is a know problem, I have changed out this part, It is to the Heater hoses, but just last week in the very cold weather, the part cracked again. Don't drive the car , pull over, shut off engine, and get car towed and fixed. You will save the engine that way.

Replace the bad radiator hose first.  Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator.  Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it.  Fourth- Check for leaks by looking for the colored dye.  If it's not the radiator hose, then could possibly be a pin hole in your radiator.  Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

SOURCE: My heater in my dodge caravan does not blow hot

First of all make sure your anti-freeze is at specification level's as well as make sure With the engine cold start the vehicle remove the radiator cap and make sure you see the flow of anti-freeze while keeping your hands as well as your clothing away from moving parts feel both hoses going into your heater core if the one on top of hot one on the bottom is cold then you have a Clogged heater core in which case you will need to flush the system . a simple garden hose will do the trick simply remove Both hoses to the heater core with the hose at the bottom line apply the garden hose until liquid comes out at the top of the other hose will probably see a lot of gunk. Also ensure that the vacuum line to the round ball under the hood is connected and not dry rotted.this will cause a vacuum leak to not allow the switch to fully engage from cold to hot. I hope this helps you.

Remove the cover plate on the passenger side of the heater box, 3-4 screws.
Unplug the motor assembly, remove 3-4 more screws that hold the motor in place and pull it down from its position. Get an aftermarket motor and installed it in the original housing with the original squirrel cage.
Installation is the reverse of removal.

Is there some type of fuse on my 2003 Dodge Grand caravan that I may need to change if it isnt blowing warm air, when the heat is on?


Hello, if its not blowing hot air its probably either the thermostate is stuck open or your heater core is stopped up.

The heater in my 2006 Dodge Grand Caravan only blows warm air while on low. If the dial is turned to high it blows cold air. What is the problem?


It sounds like the heater valve is not operating. Find the valve on the engine firewall passenger side and manually open the valve. Find it by following the 3/4 inch heater hose to the firewall where it is connected to the valve. Most likely the cable ( or vaccum hose)from the temperature dial to the valve needs replacing.

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.

Heater blowing clod air


the heater core behind the dash may be bad, it is the coolant tank for the heater system that is to say it is where the heat comes from. kinda pricey to have repaired at a dealership, if you can hear the fan turning but no heat, than it is a good possibility, or a vent hose has fallen off, get down and check under the dash
