Ford Bronco F150 Blower Motor Resistor Replacement Weak No Air Fan Hello,this video shows how to replace a defective blower motor and blower motor resistor on your car or truck. the vehicle shown in this video is a 1990 ford. Yes, it's the ground for the blower motor circuit. it's burned because it had a poor connection and the blower motor current was enough to cause the excessive resistance to dissipate heat. the heat caused the melting. a quick fix would be to jumper around the failed connection. use 12 gauge wire.
How To Replace Blower Motor Resistor 97 03 Ford F 150 Youtube Wild guess. you have some damaged wires or hvac module that is trashing all the system parts. 2009 2014 ford f150 hvac resistor keeps burning out recently had the hvac resistor burn out. blower stuck on one speed and when turning off the heater control, the blower continued to run. replaced resistor with an smp (ru893) resistor and. The average replacement cost of a blower motor resistor is between $90 and $175. expect to spend about $40 to $100 on the part and another $50 to $75 for labor if you can’t perform the replacement yourself. however, you should bear in mind that the most common reason for a bad blower motor resistor is due to a bad fan motor. The most common causes for ac fan blower motor not working in ford bronco are blown fuse, bad relay, resistor or control module malfunction and faulty blower motor. however, a bad electrical connector or broken wire, or a defect in the climate control unit can also cause the blower motor to stop working. 1. Thanks for reading–and you make a very good point. … that’s often true because something like a bad motor bearing could make the blower motor work harder to move air, which can draw more current through the blower motor resistor. when this happens, the extra current may make the resistor run hotter and, particularly in the case of a pcb type resistor like the one in the pictures above.
