I wasn't really sure where to post this, so please move if necessary...
Hey everyone, I’ve searched and searched and searched the net and forums for a solution to my problem without resolve. From what I’ve gathered, other F-150 owners have this same issue with their A/C. I’m really at my wits end on this issue, I can’t figure it out so that brings me to ask my Ford brethren for help. Onto the problem:
My truck a 2013 F-150 Raptor Scab (not like that matters). It has all the bells and whistles except a moon roof, this includes the auto climate control, which may or may not contribute to the problem.
The issue:
My A/C has been acting up for a while, maybe a couple of years now. This is what happens; it works fine one moment and then it acts possessed the next. It will start blowing on the highest fan setting and it cannot be changed with the buttons or by any means. If I try to power off the system, the A/C continues blowing at the highest setting. It can’t be shut off nor the fan setting be adjusted. I can however divert the air, such as using the defrost vents for the windshield. Although, the fan continues blowing on the highest setting. I can also shut off the compressor by pressing the “A/C” button on the control panel. If I do this, the air will stop blowing cold, but continue blowing at the highest fan setting. Ok, that’s one issue.
On other occasions, the A/C won’t turn on at all. The power is on, but no air will blow out of the vents. The blower won’t run, I can’t adjust anything. I just will not blow any air.
I’m guessing these two issues are related and they’re stemming from the same source. It doesn’t seem follow any type of schedule or any order. It does it at random and at the most annoying times despite weather, time of day or any other outside variables I can think of. It seems to be an electrical issue because the rest of the components are working fine. I just can’t seem to control them. As a matter of fact, here is what I’ve done to try to remedy the problem;
-Replaced the blower motor
-Replaced the blower motor resistor. This is the heat sink looking part located under the glove compartment. It worked fine for about a day and then went right back to acting up after replacing this part. I have taken the new resistor back and replaced it at the auto parts store and tried installing it, but the issue returns. The truck currently has the factory piece installed. I do still have a new resistor on hand to swap out if necessary, but it really does nothing to fix the issue.
-A/C Condenser is new due to a rock hitting one of the fins and spewing it’s guts out everywhere. I replaced the condenser myself, so I know it was done correctly. I had the system vacuumed and recharged by a local Firestone shop. The air blows cold when it decides to work. Also, the issue had been happening well before the condenser crapped out on me.
-Torn down the dash to get behind the control panel and inspected the connection. I actually just did this yesterday, which took a couple of hours. Waste of time. I removed the control panel, inspected the connection on the back, wiped it off and then applied some die-electric grease to the pigtail. I thought it was fixed after this, seeing as it was working fine after I put it all together. Unfortunately though, it started doing the same old dance when my wife drove the truck about an hour later.
-Tried disconnecting the battery and allowing itself to contemplate it’s existence and relearn the factory settings. This also didn’t work. Guess my truck isn’t into meditation.
And now here I am, asking you guys for help. All these attempts to fix the issue have resulted in a frustrated owner. I live in South Texas, where it gets pretty hot most of the year and have a 5 month old that I will be in the vehicle from time to time, so I need a working A/C system, as I’m sure some of you guys can relate to. The electrical system is factory stock, I haven’t done anything to it aside from adding some lights to the upfitter switches. Sound system is factory, no aftermarket stereo or alarm.
For those of you that have had this issue, did you ever resolve it? If so, how? Did you just end up throwing in the towel and just live with the seemingly possessed A/C? I’ve read that maybe a voltage fluctuation can cause this type of thing and that might be an indicator of the alternator going out, but that’s the only thing I haven’t replaced so far. It seems kinda far fetched, but I’m not sure to be honest. I’m the original owner and the truck has 84k miles.
I believe that’s it, I’ve tried to be as concise as I can be in explaining the problem I’m having. In case I’ve missed something, feel free to comment or ask so I can clarify or answer. Can someone help? I’m just about done trying to figure this bish out on my own. Thank you for taking the time to read this.
