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.

Follow the wires from the blower motor back to the blower motor resistor, normally only a few inches away and held in by a 7 mm screw. Replace it

chk the fan speed resistors mounted in the fan housing. You should be able to see the wires going into the box with 2 screws holding the resistors in place. Good Luck.

Heat


A component called a Resistor located near the blower motor controls the blowers speed. it has a plug and a couple of screws to remove. Replace this Resistor. It is usually located in between the wiring and the blower. Sometimes mounted on the blower motor itself. It can be a little hard to remove because of limited space under the dash.

1993 Jeep Cherokee blower/Heater Issue


Your blower motor could be "clogged" but I never saw one with enough debris in there to actually make one stop/ The cure for both is to remove the blower motor from the air box. if you find tons of leaves in there, clean them out. If the shaft on the motor has lots of side play, or will not run when connected hot to battery, replace it.
