Why does the heater on my 2002 dodge grand caravan only work in the back of my van?


change thermostat, how fresh is your 50/50 coolant, 50% water is what gives you heat, with thermostat, are all heat controls in correct position ? any obstructions in vent hoses, has debris fallen into defroster vents etc., are rad hoses in good condition ? weak hoses collapse and prevent flow. good luck

I do not get any heat in the rear of my 2002 Dodge Grand caravan sport. The front of van takes a long time to heat up but, heat will work after a long time. Is my rear heater core bad?


Uncover it and see if it is hot if it does your fan or switch needs replacing if it's cold and the engine is hot. diconnect hoses when ciold and put them in bucket and have someone start car and put on rear heat if water flows flush out core or replace if it doesn't flow switch is not opening vale or valve bad. I would think there is no valve and there is hot water to the unit all the time. There my be a door that opens and closes like the front heating system12_12_2011_4_57_51_pm.jpg

2002 Dodge Grand Caravan 3.8 V6, will not blow heat constantly. The heat blows off and on. I replaced the thermostat and the blower motor and dials are working. A/C is working but can't get constant...


Sounds like one of the vacuum doors under the dash are not working right check the doors and check for vacuum leaks in the hoses or the door actuators malfunctioning

Radio an cigarett lighter don't work and Blower for heat only works on High (2002 dodge caravan) can this be same problem?


blower resistor went bad causing only high speeds, "resistor" makes it slow down, maybe not all the same problem though. check fuses

Heater fan regulation


2002 Grand Caravan. The rear heater also has a resistor for the fan speed control.(3 speed) It is located under the rear passenger side plastic cover. You can take off the rear tail gate lower plastic piece and this will let you pull out the side panel. You can reach in and take out the two screws that hold in the resistor and unhook the wiring adapter. You do not have to take off the whole side panel as you can reach in from the back. The resistor unit can be bought at you local dodge dealer.
