New Factory Air Blower Motor Resistor For Ford Sterling (4C4H19A706AA / F6HZ-19A706-AA)

Has the fan in your Ford or Sterling truck stopped working on certain speeds?

Or maybe it only works on high?

That's a classic sign of a bad blower motor resistor.

Here's a brand new one from Factory Air to fix that.

It replaces a ton of OEM numbers, including the main ones: 4C4H19A706AA and F6HZ-19A706-AA.

Also crosses to F6HH-19A706-AB, 11-0435, and more.

This is the part that controls the fan speed.

Swapping it out is usually pretty straightforward and gets your heat or A/C working like it should again.

A simple, inexpensive fix for a very annoying problem.

Get your cab comfortable again.
