2003 Dodge Caravan, 3.3, 136,000 km

The heater fan stopped operating on middle blower settings ,and dealer replaced resistor. However, after two days, problem returned. Dealer suggesting blower may need replacing, but it operate fine on 'high' setting.
Any other suggestions please?

I would expect a short in the circuit to eihter have blown a fuse or blown the blower motor?

Many thanks

You could have a problem with the wiring, blower motor itself. I would do a continuity test of the wiring and the motor to see if either are grounded.

Suggested Repair

Continuity-test the blower wiring and blower motor for a ground fault; either the wiring or the motor may be at fault even though high speed still works.

Conversation Summary

On a 2003 Dodge Caravan, the heater blower stopped working on the middle settings. The dealer replaced the resistor, but the problem returned after two days and the dealer suggested replacing the blower motor, which still works on high. The owner expected a short to blow a fuse or the motor. The expert said the wiring or blower motor could be at fault and recommended continuity testing both for a ground.
