I literally had this issue going on for 2 years. Took it to the Ford dealership twice but no luck. I almost scraped the car!! My climate control as well as blind spot did not work. Well after replacing module after module, I finally sent it to a car electrician. The guy had my car for 7 weeks looking for the culprit! $2000 later, it was discovered that there had been a corroded connector on the rear passenger side between the backseat and trunk. This was due to moisture getting in through the trunk. He dispatched the connector piece and wired the two wires back together and wala!! Everything works again! These cars have so many networks that communicate! This is an easy fix but a hard find if you don’t know where to look. If I were you, I would take it to a good mechanic whom does electrical work. Tell him to start diagnostic in the trunk or backseat to find which networks are offline. This can be done within an hour. That way he can narrow down the network and zero in on checking those wires and connections instead of them searching the entire vehicle like they did mine. The culprit is a cheap peace of plastic that corroded after time. My mechanic literally replaced nothing! Just cut out the connector and joined the two wires together. I know how much of a pain this is, and I got ZERO help from anyone. So I’ll try to help you pinpoint the issue as much as possible since nobody else has solved it
