Climate Controls keep turning on and off intermittently !

[diego d]

Whether i set the climate control to Cold or Hot, it keeps turning on and off intermittently, any ideas?

You have two threads for two different issues - maybe they are related. How new is the battery?

It's 4 years old. I'm taking the car to FORD tomorrow, will update everyone

My 2018 climate control would intermittently go full heat by itself. I would have to shut off the system and turn back on to get control back. Then it would do it again. Dealer replaced the HVAC module and reprogrammed dash to fix (warranty)

My stereo will shut off and on randomly no response on touchscreen controls for anything including climate control. Did you take it to the dealership yet? Mine will be going soon.

I had an appointment last week but reschedule for tomorrow. Will let you know!

 

[A4Quattro]

Thanks, when I get mine back it will be going in to the dealership also.

I will look at the date on it. It looks fairly new and is a Motorcraft.

May not be the cause but these cars eat batteries. I would change at 4 years regardless.

Yep....they love batteries.

My date is covered by the hold down strap, I will look at it when I get it back from the dealership tomorrow. The shop I've been having do all the work on it bypassed the wire from the fuse box under the hood down to the AC compressor and that fixed it, the AC is working again.

The dealership will figure out the cycling of the stereo (hopefully just an update) and the touchscreen not responding.

The dealership said they would not do the update because it could brick the controller. If that happened they have no way to get new controllers because they are on infinite backorder. They had another Taurus and a Fusion do that recently. So my regular shop who just did a bunch of work to it said they will find me a center stack from a junkyard car and it should fix the problem as they just did the same on a Lincoln MKZ I think he said. So waiting on them to locate one with navigation. Let you know next week what happens. Otherwise I'm thinking of following instructions I found to upgrade it all to SYNC 3 compatible APIM and FDIM from a newer SHO that's been wrecked, order up the retrofit parts needed etc. He said the cost was a total of like $200. The dealership would of wanted $1,300 to fix mine if it had bricked upon update, and the parts were still available.

Had an appointment at 8am at FORD yesterday only to be told at 5pm that they didn't have time to look at the car. Apparently the 2 electricians at that location were busy all day. I have another appointment on Tuesday i will let you guys know what happens. They will also check to see why my reverse camera isn't working, I made another thread about that.

 

[A4Quattro]

I was able to fix this problem by doing a complete factory reset.

FORD called me this morning and said I need a new HVAC module assembly, they are now checking to see if it's covered under my warranty (premium care).

 

[diego d]

they are replacing it free or charge as it is covered under my warranty

the only bad news is that it takes 15 business days for the part to come in from the states.

2013+ can be upgraded to SYNC2. Yes you need the APIM and FDIM, plus a GPS antenna wit Fakra connector and if you want to use Carplay or Android auto a new USB hub, trim piece, and associated harness. Ford only sells the pigtail but Tech sells premade harnesses.
