Year group and connector shape
F150 blower resistors are mostly tied to one generation. Earlier trucks through 1996 use older HVAC designs, 1997-2003 trucks use another, and the 2004-2008 and 2009-2014 trucks each have their own. Do not carry a part from one group into another, and do not assume an F250 part matches.
Cab, bed, engine and 4WD are not reliable guides here. One listing excludes trucks with dealer-installed air conditioning, so read the notes. Look at your old part. Compare the terminal count, connector keying and screw hole spacing, and check whether your truck uses a simple resistor card or an electronic blower control module. Those two do not interchange.
Fan only works on high
The textbook F150 symptom is a blower that runs only on the top setting. High speed usually bypasses the resistor, while the lower speeds run through it, so a burnt resistor kills those settings first. You may lose one or two middle speeds before the rest go.
If the fan does not run on any speed, look further. A dead blower motor, fuse, relay, switch or wiring fault can cause that. A burning plastic smell or a brown, melted plug at the resistor means heat damage that needs fixing beyond the resistor itself.
Pigtail, access and testing
On 2004-2014 trucks, the resistor sits in the HVAC case on the passenger side, reached from the footwell or by lowering the glove box. It is commonly held by two 8mm screws, so the swap is quick.
Inspect the connector before plugging in the new part. Melted or corroded terminals will cook a fresh resistor, so replace the pigtail when you see damage. The Dorman resistor kits listed here suit that repair. A noisy or tight blower motor can also overload the resistor, so check it too. Test every fan speed before you refit the trim.

F150 questions
Why does my F150 blower only work on high?
High speed usually bypasses the blower motor resistor, while lower speeds pass through it. When the resistor burns out, only high still works. Replacing the resistor, and the plug if it is melted, usually restores the other speeds.
Where is the blower motor resistor on a 2004-2014 F150?
It mounts in the HVAC case on the passenger side, near the blower motor behind the glove box. You can reach it from the footwell or by lowering the glove box. It is commonly held by two 8mm screws.
Should I replace the connector with my F150 blower motor resistor?
Replace it if the terminals look brown, melted or corroded. A damaged plug causes heat that can burn out the new resistor quickly. Some listings are resistor kits for exactly this repair.
