Hello,
I have a 2011 F150 FX4 V6. I am having an issue with my blower motor. My blower was stuck on the same speed so I changed the blower motor resistor as suggested by many sources. After replacing the resistor, the motor isn't working properly. If I turn the switch on, the motor works perfect as it should. When I turn the truck on, the blower turns on and off. It stays on a couple seconds and then turns off about 10 seconds and so on. Can anyone help?

Thanks!
