Ford Blower MotorsBy Elina | Published on Dec 03,2015
We have featured both Delco and Chrysler heater blower motors in previous issues. This month, we'll discuss air conditioning and heater blower units for Ford, Edsel, Lincoln and Mercury.
Ford used several different types of blower motors. Most early and non-A/C units used recirculated interior air, while most A/C-equipped vehicles used motors that were vented to pull in outside air. Some Lincolns and station wagons used underseat blowers, and several Lincolns used dual fan motors.
The list of original-equipment part numbers and interchanges is extensive. There were 49 OE part numbers listed in the 1954-'66 Hollander Interchange alone. However, replacement motors can be boiled down to a much simpler list using just a few simple replacement motors. They may not have the OE terminal plug on them, or the motor length is not identical, but they do fit, and perform the task adequately.
Part numbers referenced here show several root numbers: 18527 series numbers are for the replacement motor only, while 19805 (and 19846) series numbers are complete motor and wheel assembly numbers. Applications where "with A/C" is shown apply to factory-installed A/C systems; dealer or aftermarket add-on air conditioning used non-A/C or dual-shaft blower motors.
