2003 Dodge Caravan 6 cyl Front Wheel Drive Automatic 70,000 miles
1. Although the fan is turned on, air does not come through the vents. It seems to work at first and then stops as you after you have driven a ways. Once it stops coming through the vents it does not start working again until the car has been turned off and sitting quite a while. You can hear the fan but no air/almost no air from any vent.
2. There is a hissing sound coming from under the dash. It is located under the glove box.
3. When the fan is working and air coming through the vents, if you slide the temperature controls to the coldest settings on the left, it blows very cold air and seems that the air conditioning is on even though the air conditioning button is not on.
Took it to the Dodge dealer and they 1) Replaced the blower motor they said had a short in it; 2) Replaced a broken door in the HVAC unit under the glove box. Cost $500 but did not fix problem.
While this problem was occurring, I looked under the dash on the drivers side and had someone rotate the knob from floor to defrost to out the front of dash. I could see the mode door actuator moving so that does not seem to be the problem?
Problem occurs whether you are using the heater or air conditioner.
Something electrical overheating? Air seems to be blocked at the fan.
Again, Works fine when the car is sitting overnight or for a long time and then stops after you drive some distance.
Thanks in advance for your help.
have the same problem?
