Was looking at another forum and found a thread about upgrading the heater blower motor on a heater with the motor mounted inside the cab and not through the fire wall. The guy used a 90 Blazer motor, then installed a 3 speed switch and heater switch resistor to make it all work.
Was thinking of trying this for 2 reasons. 1: more efficient motor 2: the Painless harness I got is set up for the 3 speed switch with the resistor and 1 wire to the motor and not the old Hi/Lo 2 wire motor and toggle switch that was stock on the 75.
Was wondering if anyone here had any experience with this or any suggestions or words of advice?????
Thanks - Bill
