Great videos as usual!! Do you have an affiliate link on amazon for the version of this part for an a/c unit with automatic control instead of manual? 07 Expedition, please. Thank you!

[@sturmovikcarr7289]

Much appreciated. Just changed mine out. Not hearing the fan blowing full blast is great. No more nagging as to why is it so cold/hot in here is even better.

[@plasteralex]

initially my blower was stuck on low, I replaced it with an aftermarket part, and it was then stuck on high. I got ahold of a motorcraft part and that fixed all the issues. Cheap parts will fail over and over in this instance.

Great info This is my exact symptoms. I am stuck on medium speed. I will change out the controller.

[@briangross6726]

I had this same problem on my Honda Pilot a few years back and found a video showing an alternative to replacing the whole $100 blower resistor module was to replace an $0.80 thermistor inside the module. This gave the idea that it was probably just a temperature sensitive component once again inside the module. I took it apart and found a power MOSFET with the part number P14155 from STI Electronics. So I de-soldered it from the board and replaced it with a new one ($3 plus shipping) from DigiKey. Sure enough that did the trick!

[@noahvaldez1968]

My 06 is having blower stuck at max. I replaced the motor resistor listed and still have current issue. Any advice ? Could the new replacement been a dud?

[@ozzstars_cars]

In this day and age it's amazing how blower motor resistors can't take the heat long term.

[@balexander8]

I replaced both the blower control module and the plug. Now my blower will not turn off. I can change temps and where the air is coming from, but have no control over the speed of the motor. It even blows when I turn the fan off.

[@oldfarthacks]

This is a pulse width modulated device. There are as you can see 4 wires, they are power, ground, control and then the lead from the blower motor, which this module will short to ground. There is a power transistor that the control panel mounted in the center of the dash is turning on and off quickly to run the motor. This is why the heat sink on the back, that transistor gets HOT. I'm dealing with this in my Navigator right now. When the car is running and the AC system is on, changing the temp will change the blower speed. But if I turn off the system, the silly thing goes into full speed ahead. So I ordered a real cheap one from Amazon that will be here tomorrow along with a new relay, just in case that is the issue. For 37 bucks, it's a quick way to check the system.

[@mikedrabek9733]

Do not use cheap Amazon part! I learned the hard way!

You mention frying the new module if you test run it before remounting it in the housing. I assume this would take a bit of time and that you could at least get away with running for just it a minute beforehand?

[@lherr0214]

Thank you for the help great video.

[@billyyoder8171]

Thank you Brian. Good job. I appreciate your videos. Does this speed controller receive a variable analog voltage signal from the control head or is it a digital duty cycle signal? Which ever analog or digital, do you know what the signal voltages will be? Thank you

[@shinerbockdoc]

Great Video. My 2014 F150 Plati has same issue. Used all OEM parts for resistor, blower motor, Bussman 40A vinyl fuse, and relay and harness is good. Blower stuck on high. Upon removing the blower motor, there was a 1’’ cylinder piece of plastic inside the fan scroll rolling around. Stuck phone camera in there and took pics, but can not see or feel where this piece broke off. When I feel inside where the BM connnects, there is a plastic half moon shape door with 2 pivot points - this rotates about 60-90 degrees to allow airflow. The broken piece has hole/fitting with notches….I am think it is a pivot point for this fan switch speed selector actuator- . Gonna search and come back with deets on what I find.

[@sarahthompson6240]

It’s from the recirculating door above the blower motor. The stepper motor attaches to that piece and sheers it off. There is a video on KZbin that shows how to replace it without removing the entire dash.

[@wiambekker358]

Very nice vid.

[@kendricktilley5550]

I changed mine and it just blows harder even when off, any suggestions

[@connorbyer6527]

I replaced this part twice. The first time my AC was completely off. I replaced the controller and it turned on, but still stuck on high. I replaced the part on warranty. I made sure to put it in properly. It worked for about 5 seconds and then got stuck on high again and is still having the same exact issue as this video. Could there be a short? Have you heard of this happening before?

My speed knob won't turn correctly. Goes to high and back in the middle. Won't turn back to the low setting at all like something is stopping it from turning. It's a 2013 and I put a brand new climate control bezel and everything in this summer cause all the buttons were junk.

[@sgt100702]

I just replaced the MAP sensor on my 2013 F150 FX4 3.5L V6 Twinturbo, and in doing so, I disconnected the negative battery terminal to do the swap. When i hooked everything back up again and turned on the engine, the air was blowing full power, even though the power was off to the climate control. This wasn't an issue right before I did the MAP swap and battery disconnect. I tried disconnecting the negative terminal again for 12 minutes to see if it would reset, but it didn't work. The first search I did online led me to this video. Would it be best to replace the blower motor speed controller in this situation? I'm thinking the battery disconnect somehow scrambled the control module. I believe the AC was on when I turned off my truck after coming home with the new MAP.

[@sgt100702]

UPDATE: I just swapped out the blower speed motor, problem fixed!! Thanks for all your great videos, saved me $$$$$ over the years.
