I don't even know where to begin.. It seems the problem is originating from the My Ford Touch but I can't be sure. (Truck details below)

It all started about a week ago when I noticed my heated seats stopped working. I then noticed my climate system was not working either. No heat, no AC, no air moving through the vents at all. Sometimes it gets stuck on AC mode, sometimes on defrost, but never moves any air (except for one time when it went really wonky and started blasting AC, then shut off, then on again, all by itself).

I also noticed it either won't display the outside temperature or displays the wrong temperature . And only sometimes will it correctly locate me on my navigation map.

And I also noticed that when I stick the key in or take the key out of the ignition, my seats don't move like they used to. It used to roll back when I shut the engine off and would bring me closer to the wheel when I put the key in. It isn't doing that at all anymore, no movement.

This all has me thinking it's some kind of computer issue and not a heater issue since so many weird glitches are happening at once. I have no idea what the issue could be as I've been having trouble finding a forum on this. I did a Master Reset on the My Ford Touch screen but that fixed nothing.

Anyone have a clue?? This is my first Ford, my first truck. I bought it used about 4 months ago with 32,000 miles on it. Drove it from California to NY, picked up a camper along the way, with no problems. Of course now that it's freezing in NY does my heater stop working. Sucks.

I'd take it to a dealer if it were me. Sounds like some computer brain somewhere in the truck has gone bad. They should be able to get codes and tun tests. Could be chaffed wires somewhere, but probably unlikely.

 

Do you have any check Engine lights on? Have you tried taking it to an Auto Zone or to have it scanned for any codes, might give you a point to start. Dealer will scan it for codes for sure, just due to the symptoms. I did see you didnt mention anything about a check engine light on so I am going to gather there isnt one on.

You didnt have anything done to the truck where the batteries would have been disconnected or replaced a battery have you? Just wondering. I was thinking of the climate control issue and it almost makes think of a vaccum leak or maybe a blend door stuck open which might be why there is no heat, I believe the system automatically defaults to the defrost position hence no heat.

But that doiesnt explain the my touch issue and the map not picking up where you are, that sounds like the system lost touch with the GPS antennae, so I have to think inline with seville09's thinking of the computer issue, hence why I was wondering about the batteries being changed.

You havent added anything new electronically have you? Have you had a look at your fuses that control those various function to make sure they are good and nothing is blown? Made sure your relays under the hood are all seated and fuses in there are all good? Might be worth a look. Cant say I have heard of this issue before, but there is always a first time

 

Thanks for taking the time to respond! I haven't checked my fuses but I will. (once I figure out where they are and what to look for..like I said, first truck, know very little about cars)

The only thing I can think of that changed electrically was that I disconnected my camper. I had it connected to the 7 pin plug in the bed. But I know for sure it was working after that, as I drove up to my parent's for christmas. The only other thing I disconnected was a backup cam I bought for the camper that plugged into the connection where the tailgate camera plugged into (I don't have my tailgate on since my camper is a slide-in). But again, I know it worked for at least a couple of trips after I disconnected those two things.

And no, no check engine light.

I left a couple of messages with the local Ford dealer last week but no returned calls. Just going to have to keep calling and have them check it out I guess.

 

Have you cheked your coolant level to make sure you still have coolant? If there is no collant that would be an issue, I assume you did this, but thought I would mention it.


You will have one fuse box under the driver side dash on the wall next to the door above the driver side foot well, the other fuse box is on the driver side under the hood its is kind of a long square box and you will see a bunch of wires in a bundle running into the underside of it. in that box you will find fuses and relays.

If you look in your owners manual somewhere in there should be a fusebox layout with the corresponding location numbered on it, then that will tell you what amperage the fuse is and what it belongs to from the description in the manual.

You should see a brief descipition in the manual of what the fuse looks after :ie #spot 19 ignition 20 amp fuse and so on like that. I would look for ones that have to do with some of the issues your having.

The dealer has IDS which is pretty indepth tool and they can look up codes that may not show a check engine light not to mention they have a lot of testing features and on IDS and bidirectional controls they can use to test functions of the truck. so sure they will be able to help figure it out.

Reason I asked about anything electrical because I am just wondering if something caused a short to pop a fuse, might not be the case, but one never knows

 

With the miles you say you have on your truck , I would think it would still have a warranty , and you should take it to the dealer .

 

I know you said you did a master reset on the Sync system, but I would do a master reset on the whole truck too. Disconnect both batteries and let all the systems start fresh. If this doesn't help the problem, maybe have the batteries checked out at an autoparts store or something. A bad battery can cause lots of weird things to happen with the electronics in these newer vehicles. Just a thought and is where I would start.

 

thanks for the tip! Would you mind telling how to go about disconnecting my batteries and where those batteries are located? I didn't realize I had more than one. I'm sorry.. I really know nothing about cars. I'm willing to learn but just need a little guidance.

 

take it to a dealer.....period. If you don't know where your batteries are, you shouldn't be trying to diagnose and fix this.

 

Lol thanks.. I have an appt for next Monday. I'll be sure to post with an update as to what the issue was. I'm really trying to learn as much as I can about this truck so thanks for all the tips.

 

Well hope that they will be able to solve this for you without too much if a nit to the pocket, do let us knows what they find out, someone else may have this same problem down the road, always nice to have the info so other folks can have a look and see if your solution might work for them. Good luck!

 

Okay so my truck is still in the shop (it's been 4 days now). Took it to my local Ford dealer. They said they had a really hard time diagnosing the problem but they are about 95% sure that it's a faulty GEM module. They have to order the part and will only be able to tell if that's the solution by installing it and testing it out. They said the part alone is $750 + labor. Ouch! Good thing I have MaxCare extended warranty. I only have to pay $300.

I will also add that the night before I took the truck in, I plugged the engine block heater in. It was the first time I did that. It's winter in NY so I probably should have been doing this all along. But I started my truck the next morning and everything was working! The heat came out warm immediately when it hadn't been working at all before. The temperature gauge, the GPS, the seat position memory, the climate control and heated seats.. all working normally. For the first time since I had the issue. I asked the service guy if this would have anything to do with the problem and he said no. So maybe he was right and it was just a coincidence that it all worked the one time I plugged it in. But I can't help but wonder if the problems were at all related. I will also add that this is probably the first winter the truck has ever seen. I bought it in California but it originally came from Tennessee. Maybe the cold weather had some sort of affect on it?

 

Plugging the truck in really should have had no affect on your other issues, unless by some extremely remote chance a wire or ground by the plug was loose and the act of plugging it in and unplugging it somehow pushed it back into place. I think it was just coincidence though.

It's possible that your battery isn't at full charge or alternator isn't working right, and uding the engine block heater masked the problem (battery didn't have to work as hard), but I doubt it. Plus the dealer can test those quickly and easily.


I'm in NY and only plug my truck in the few times when it's double digits below zero. Otherwise just need to make sure you have a good battery with high cold cranking amps.

Good luck.

 

I have been having a problem with my 2013 Ford F-350 SRW 6.7L. Whenever i am driving it will randomly sputter but does not loose any power. Once it acts up i can accelerate with no issues. The truck has 198,000 miles on it and am wondering if it is a fuel related problem or something to do with the EGR. The check engine light isnt on and does not run rough at idle. Also the truck is completely stock and i pull a single horse trailer daily. Thanks in advanced!
