F-150 High Speed Fans Running and Poor A/C Cooling (Expansion Valve)

Рет қаралды 45,226

Hi folks, this is a re-upload. I accidentally deleted this video (after over 50k views!)
This 2014 Ford F-150 had high speed fans roaring constantly and the air conditioning was barely blowing cool. I found a lot of information online about changing the expansion valve to cure this issue and sure enough, it works.
Since filming this video last year, I’ve done this same repair a half-dozen times with hood success on F-150’s from 2013 to 2016.

The brake line trick is all the money. Genius.

Awesome video. I bought the valve and took it to work with me so I could find the right bolt to use like you did with the brake line. We have a huge assortment of bolts in our tool crib. Found the exact size (in metric) and cut the heads off so now I can change out my valve.

Thank you!!!! I bought an 11 at auction and the AC held a charge, but no love. Anyways, followed your procedure and worked great (dont know why i was sure the brake line needed an SAE thread, once i cut a metric thread i was golden)

Make sure you refill it with exactly 24oz of refrigerant. I’ve seen a few people overcharge slightly and see similar symptoms even after replacing the valve.

I just wanted to add that my fan was constantly being forced into high mode and this video made me realize my system may be over pressurized after recharging. I released some pressure and my issue was resolved. Thank goodness! I was ready to replace the txv.

Thanks for the video. I am about to change my expansion valve as well. My ac is semi cold and the compressor stays running continuously and doesn’t cycle on and off. I was told it’s the expansion valve not closing and it needs to be replaced.

@RedeemedMechanic Жыл бұрын

Haven’t seen that type of valve failure on these trucks, but it won’t hurt to change it. While you’re doing that, add a small amount of PAG 46 oil with fluorescent dye, just in case you have a leak somewhere. Make sure to put the system in a vacuum for at least 20-30 minutes to boil out moisture. Then charge with exactly 24 ounces of R134a. These trucks are fussy about the charge level. Best of luck!

I see the kit comes with 2 washers. Is that all that is needed to change the Expansion valve? What about the back side where the block gets screwed into? I have a 2016 F150

@RedeemedMechanic 7 ай бұрын

You’re gonna want the other two sealing washers. I don’t understand why they don’t include them. I keep a kit with multiple sizes so I had them on hand. A lot of times you can buy an “installer kit” that will have every sealing washer and o-ring for the whole system for very cheap.

guess Im old school, two questions, 1 I guess no one uses fender covers any more? and why couldnt you use a threaded rod or a bolt with the head cut off, may be a little easier to get than a brake line , then thread it, or am I missing something?

3/16” SAE thread isn’t the same as 5mm X 0.8 thread. It would be a bad idea to use the wrong thread pitch and risk damaging the threads on the little block plate. Nobody wants to deal with cross threaded bolts when doing that job.

@RedeemedMechanic Жыл бұрын

I recently looked at a friends truck (2013) with similar complaints. Turns out his evaporator is covered in dust and grime because these trucks don’t have cabin filters. We brainstormed a few ideas on how to clean the evaporator without pulling the dash, but since he’s a bit of a mechanic himself he will probably try it himself. If you have a digital inspection camera you can remove the blower motor resistor and have a glance at the condition of the blower side of the evaporator. If it’s really fuzzy looking, you probably have the same issue.

@@santiagodavila1426 no, it meters the refrigerant and controls the flow to allow system to pressurize correctly so your evaporator which is inside can get nice and cold. A fan blows across the evaporator, creating that nice cold air. Your fan speeds are controlled by your computer, as is just about every single thing on this truck.
