2013 Dart Rallye perfect fit. Fan would sometimes not turn on but I could hear A/C pump turn on & off so I thought this Resistor was it. Pulled the old one out it looked very corroded installed new one - Still same problem. When we started car the blower would either work a bit or not at all (if it did work it was surging up & down on the highest setting). As it turned out the blower had a faint vibration, we could hear it on low speed, ordered blower installed and all fixed. 2013 Dart has 100,000 miles on it. Ordered and Changed filter also which was filthy.
