Hi I am a new member and I have a problem. We have a 2010 Dodge Caravan and the heater/ac fan will not blow. We have tested the motor and it is fine. Changed the fuses. has anyone run into this problem, is there something else we can check?

 

Welcome to DF! I will move this to the Caravan section.

 

Hello,

This is the 2010 Dodge Grand Caravan? What engine does it have?

 

Power flows from the TIPM to the motor. The ground side of the motor flows through the blower motor resistor and then through the control head before it can reach ground. The control head sends a digital signal to the TIPM to provide power to the motor. So check the dark blue wire coming into the motor to see if it's getting power when you turn the blower on. If not, check at the TIPM on the dark blue wire. If still no power, then you have either a digital bus problem, a TIPM problem, or a control head problem.

If you do get power on the dark blue wire, check the blower motor resistor to see if you have continuity. Replace if there's none.

 

Does the blower work if on high only?

 

Has this been solved. I have the same problem.
