A/C Question

The other day, the lower two levels of my blower went out. I still get air on the upper two but not the others . Does anyone know if there is a separate fuse for these or where I should check to get this fixed?

TIA,
Brian

Odds are your blower motor resistor (19A706) is shot.

Is there a way I can test this? I have a multimeter where can I find this resistor?

The blower motor resistor is located on the bottom of the heater plenum (case) on the passenger side of the cabin near the blower motor. You can check it with a digital volt/ohm meter/multimeter. Check for excessive resistance or open circuits. Do this check after you have removed the resistor from the plenum. This will allow you to check each resistor coil individually. Ford p/n 4l3z.19a706.aa. Check our website for your price. Dan.
