Random blower motor functions on and off
My 2014 ram 1500 blower motor randomly cuts in and out. I have changed blower motor and control switch and it’s still cutting in and out.
The fourth generation Dodge Ram was introduced at the 2008 North American International Auto Show in Detroit.
If you have changed the blower motor and control module, you likely have two remaining possibilities:
1: Your blower motor resistor has failed which can cause an intermittent connection as the resistor heats and cools.
2: You have a loose connection in your wiring harness. Check all the pins are firmly in place in the connector.
