2003 F150. HVAC blower is not working. It worked intermittently for a few days (when it work it works on all speeds hi, med-hi, med-lo, lo), but just quit completely now. Bad blower motor, resistor, where do I start? Thanks in advance.

 

Hey did you ever get an answer? I have an 02' FX4 which is starting to have those same problems. Thanks.
