Question about 2001 Dodge Caravan
I have a 2001 Dodge Caravan Se 4cyl 2.4L Minivan. For the past two winters I have had no heat. Last summer my car overheated so I had the radiator replaced because it was clogged beyond belief. I figured whatever was clogging the radiator must have clogged the heater core since the coolant flushes through there as well, so a few days ago I flushed the heater core. I cut the hoses to the heater core and I left the top and bottom ports unplugged. I put a garden hose to the top connector of the heater core and flush dort, debri and rust particles out of the bottom and then I did the same to the bottom connection in reverse so whatever was lodged in there would get jumbled up and spit out. I proceeded to run the water through the heater core until it came out clear, dirt and rust free with a full force steady flow out of the other end. Then I bought new hoses and reconnected the heater core to the motor. Now I get a little heat for 5-10 minutes on a medium fan setting, but after that it goes ice cold. Any higher then a medium fan setting it goes almost instantly cold. I do not have a head gasket problem or a coolant leak, because I had it checked by a mechanic. What else could be the problem with the heat? Could it be something like a vacuum hose or maybe a vent door not closing? If it helps any you can hear a sound of what is believed to be a vent door snapping shut on the lower passenger side. Im freezing my toes off in the van so any and all suggestions and advice is greatly appreciated...Hope to hear from somebody soon, I dont know how much more of this cold I can take. thanks in advance.
The problem with no heat is caused by air temperature control blend door motor in the dash air ducting, this door moves in different positions to allow air over the heater core or to allow air over the AC evaporator core or a mix or blend of the 2 air streams to obtain the desired outlet temp.. The bad news is the dash must come out to replace this actuator.
