SO i have what i am assuming is a fairly small issue with my AC in my 2012 F150. I am having an issue with the low volume of air coming out of my vents. I can hear the blower blowing normally, and the air that is coming out is as cold as ever, its just not blowing as much air as it normally does. I am assuming it is some blend door that is not opening all the way. Just wanted to see if anyone has been able to fix this themselves before I go pay a shop $100 for a $10 fix.

Sucked a bag from your floorboard into the blower opening causing a restriction

Does it have a cabin filter? If so, how long has it been since you replaced it?

From AgCo Automotive (Baton Rouge) website of frequently asked questions.

quote:

My air conditioner does not blow as hard as before?

If air volume is lower than normal on all fan settings, suspect a restriction in the system. If the vehicle is equipped with a “cabin” or HVAC filter, check and replace if needed.

Another common restriction is small plastic shopping bags that are drawn into the system from outside. Driving in parking lots, these bags are often pulled into the air intake, blocking the air flow.

The evaporator core can also become restricted. This is common on vehicles without “cabin” air filters. A professional cleaning may be necessary if this is the case. Evaporators are very easily damaged and normally quite expensive to replace.

A malfunctioning mode or blend door, in the duct work can also cause lack of air flow. These doors open and close to duct air through the system. They are operated by servo motors and sometimes vacuum controls. When they malfunction air flow may be blocked.

Ain't that the damn truth. My company truck is a 2011 and has the worst AC system I have ever experienced. Full blast MAX AC is about the only way I can run it in the summer.

Ford hasn't put cabin air filters in the F series trucks since 09. You can buy their cabin air filter kit that adds one from the parts dept. though.

ETA. If you go to AgCo website and send Louis an email, he’ll respond to your question personally within 24 hours, usually sooner. If this happens to be a common problem with the AC on 2011/2012 F150s he can likely narrow it down to the most common issue they see in his shop. The more details you can provide the better.

Following up, my model year f150 doesn't have a cabin air filter so that's not the issue. Dug around on F150 forums, apparently The blend door actuators and mode door actuators tend to fail as they are not well made. Luckily, the mode door actuator that i think is my problem can be accessed and replaced ($25) from the foot well of the drivers side and I wont have to remove the dash to get to it.

Louis with AgCo has a weekly radio program I listen to and actuator failure is a common problem with the issue you describe. Seems most vehicles have about 4, with 1 or 2 easily replaced and the others requiring the dash be pulled. Sounds like you maybe lucky on this one. Vehicle forums are a great source of information for this type of troubleshooting. Good luck with the repair. Make sure you use a OEM part.

even the difficult actuators to get to aren't that bad. There's 3-4 7mm bolts that hold them on. You can get to 3 of them relatively easily. Just use a screwdriver to break off the last corner of the actuator and pull it out leaving the bolt in the evaporator case. Just notch the new actuator hole to slide over the bolt left in the case when installing.

i was coming here to say check the actuators, it is a common problem on that year. i had a 2012 that would shut off the flow if it was turned on more than half speed. it was the blower motor. 3 bolts to undo and 1 plug and i was back in action.

Get with the Ford shop and check for a recall on your truck for the vacuum pump. My 2011 had several issues vacuum related such as the a/c not blowing in the upper vents, the 4x4 front hub actuators going out one at a time and the brakes getting hard on a hard braking release and another hard braking. After I traded it in I got a recall notice from Ford for the vacuum pump, go figure!!

This would be the first place I'd start.

That’s what it sounds like. Very common issue on older GMCs too. They can spin too far and are simple to reset/replace. Dig around on YouTube. There’s a guy that walks you through fuse reset method and (maybe same guy) how to spin the actuator back to original position using a 9v battery.

Hopefully yours won’t be as hard to get to as the one under my driver side dash.

I had to replace my Blend door actuator on my 2011 last year. Mine would made a loud clicking noise when I turn my A/C all the way cold.

Why would Ford use a cheap piece of plastic for that and not expect it to fail I have no idea. Money I guess is the only answer.
