No AC, airbag, outside temp, tailgate when hot weather

[Beyondonedge]

Hi,

 

Just joined trying to see if I can find a solution. I apologise if there is a post with a solution somewhere.

I have a ford edge 2017 which I bought used back in November 2024. Not every single time but on several occassions when the weather is hot I get the following symptoms:

• No AC, options grey on touchscreen

• FCIM appears completely dead, no buttons will work BUT radio if already on from before can be controlled from steering wheel

• No external temperature displayed on touchscreen or IPC. Instead it reads "--"

•Airbag icon/light  on the dash

•Electric tailgate will not open

After reading post on forums both about the ford edge and other models  I thought maybe the FCIM may need replacing. When I disconnect it I can recreate all the symptoms except from the tailgate which works fine. This leads me to think it may be a connection issue somewhere which the heat triggers? Frustratingly, it is always when I really need to use the AC and instead have to stick to keeping the windows down on the motorway.

Has anybody come across this and found a solution? I want to avoid the bill from the local ford dealer if I can.

Can anyone direct me to the connections involved and their location so I can check them?

If it is of any use the part number of my FCIM is HM2T-18E245-ARA

Thank you
