Blower unit failure

Asked by Aug 20, 2015 at 12:36 PM about the 2008 Ford F-150 XL 4WD

Question type: Maintenance & Repair

Thanks in advance if you can assist me!




I have a 2008 F150, 4.6 V8



While driving with my AC on and fan on high, the fan (blower) briefly cut in and out and then blower stopped working.  I checked the blower fuse and it looks good. I checked the Blower relay and the guy at autozone said if the relay is bad then I will hear clicking under the hood while the motor is running. I hear no clicking. I looked on the internet and found some videos showing how to replace the Blower Motor Resistor so I installed a new Blower motor Resistor. The blower is still not working. While driving on the highway with the AC on there is a little cold air coming out of the vents however, if I switch it on inside air source (max AC) then the air flow stops. Whatever is under the glove box is getting cold and the AC is working.



Does anyone have an idea how I can get the blower working again?



I have never changed my inside air filters and they may be clogged but would that stop the blower unit from working?  




Can anyone direct me to a forum that can help?

sounds like the blower motor itself is no good, you can check with a meter to see if you have power at the motor.
