Question about 1996 Dodge Caravan
Dodge Caravan 3.0 V6 1996. Inlet and outlet of the heater core get hot. When i squeeze the inlet or outlet hose, i see the level underneath the radiator cap go up and down. Air blower works fine, but it won't give me warm air. How do i check the coolant pressure? What should the pressure be? Doesn't look like i have a leak in the system. Could it be a fault in the cold to warm switch? Or maybe the little door that should direct the air over the heater? Hope we can fix this problem. Cheers, Joey.

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.

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.

Testimonial: "Helpful & quick feedback! Thanks! "
your sure you installed thermostat correctly and no leaks around it ...are both top and bottom hoses hot going into and out of the heater-core and all fluid temps are at specified levels ...
you may also have an air bubble which when back-flushing may occur was the vehicle getting heat prior to reinstalling another thermostat / and while fluid was replaced into the radiator circulation /flow of exchange from the motorto the radiator are presenty working no vacuum lines are dry-rotted causing a vacuum leak ..hmmm you can hear the heater flaps open and change from the dash defrost to floor to vents etc ok that sounds like its working but check with the cap off to the radiator for proper fluid levels and that the fluid is exchanging and both the top and botto hose into and out the firewall are hot if the top is hot and the bottom one is coldyou may still have a lot of sediment /gunk in the core itself and reflushing the core is required and remember not to use full force when doing so or you risk rupture to the unit /core with the motor off remove the 2 hoses face the bottom or top on towards the catch pan because its illegal to disburse it onto the ground and whether your back flushing it or just running the water through you will also dislodge the air bubble as it fills with water after your sure the above is all looked into check to ensure the flow of fluid is present ...this is my starting point on your issue ...

Way up under the dashboard, is your blend door lever that is opened and closed by the termperature control cable. We often find that the part that holds the cable sheath has come loose and no longer holds the sheath such that the cable inside will move the lever to open the door. I show the location and then a close-up of the mechanism below. You need to check to see if the cable is actually moving the lever and if not, reclamp the sheath so that it does. Please let me know if you have more questions.
