Heater blower switch problem
08 F150 heater blower motor switch only blows on speed setting 3 and 4. 1 and 2 are completely non responsive. Anyone else had this problem or have heard about this problem? I thought maybe it could be a fuse or something but not sure. Any info would be greatly appreciated.

x4 resistor
Common issue but is often a sign that there is an issue with the fan motor itself. It is a cheap fix so go ahead and just do the resistor but if it goes again, change the fan motor.

Mine just blew for the second time. I picked up an eBay special the first time, and it lasted a year. Now I bought one with a limited lifetime warranty. I'll keep changing it out, instead of putting a new blower in.

only a matter of time before you start blowing fuses

I don't think the motor is very expensive or difficult to change.
