Kia Troubleshooting Questions? Ask a Mechanic
Hello, the blower stops working on all speeds? Did you replace the blower resistor connector? When the blower stops working if you wiggle the harness does it start working again? Have you inspected the blower switch and connector?
Ok since the blower motor connector has been replaced, does the new one show signs of it starting to melt or overheat? You replaced the wires with the conector correct and not just the connector shell? Do you have the motor wired correctly so it spins in the correct direction, not reversed polarity?
Ok so im assuming the dealer used dealer parts. If they did the original diagnosis, it should be on them to get this resolved. There are no known technical service bulletins other than an issue with remote start operation of the fan which is a wire harness repair(which the dealer should be aware of). Either the fan is a defective part, which it would be hard to believe after multiple replacements. Or an issue with the blower switch itself which is the only thing left in the circuit other than the blower relay.
They should have wired it correctly. It doesnt give me the direction the motor spins but shows me a picture of how to wire the motor.
most blower motors have an external air inlet hose that directs air back into the motor armature to keep it cool. Make sure if this motor has this feature, that the air inlet is clear and allows air to flow into the motor to keep it from overheating
