Remove the three 5.5mm bolts and drop the blower motor down. Undo the electrical connector from the resistor to the blower. With blower removed you will be the blower motor resistor. Undo and remove two forward retaining screws to the resistor assembly and loosen the rear since it is slotted. Remove and replace the resistor. Reverse procedure to install.
