This is the replacement heater blower motor I installed in my 1966 Mustang. The original was old and grungy, and rather than test it and risk tearing the heater box apart again, I replaced it while the box was out.
It fits the 1965 and 1966 Mustang heater box and bolts to the housing with the original mounting points.

Blower Motor at a Glance
- Replacement heater blower motor for 1965-1966 Mustangs
- Motor only, so you reuse your original fan cage
- Cheaper than buying the complete motor and fan assembly
- Mounts with two bolts to the motor housing
Why I Went Motor-Only
Mustang blower motors are sold two ways: the motor alone, or a complete assembly with the fan cage. The motor alone costs less, but you have to get the fan cage off your old motor shaft.
Mine came off after a WD-40 soak, a few gentle taps with the butt of a screwdriver handle, and a quick wire-brushing of the rusty shaft. If your cage won’t budge without prying, buy the full assembly instead. A bent cage will vibrate badly once the motor spins up.
Who This Motor Is For
- Anyone with a dead, noisy or tired original blower motor
- Owners doing a full heater box rebuild
- Anyone whose fan cage comes off the old motor cleanly
How I Installed It
- Remove the four nuts and pull the old motor and fan out of the heater box.
- Free the fan cage from the old shaft without hammering steel on steel or bending it.
- Mount the new motor to the housing with its two bolts.
- Install the fan cage on the new shaft and tighten the set screw.
- Install the motor in the box with the screw leads facing the upper part of the box.
