Linea solar sensor error and weak heating

Hi, I have a 2022 Fiat Linea, diesel engine, with about 154k km on the clock. Recently, I've been getting an error related to the solar sensor. The car's computer stores it in the error memory. I've also noticed that the heating isn't as effective as it used to be. I suspect it might be related to a defective cable or plug connection, but I'm not sure where to start looking. Has anyone experienced anything similar?

A 2022 Fiat Linea owner is experiencing a solar sensor error and weak heating. The issue may be due to a defective cable or plug connection. Another owner with a similar problem found that a faulty connection to the sunlight sensor was the cause, which was resolved by a workshop. The suggested solution is to have the vehicle inspected by professionals to address the sensor connection and restore proper heating functionality.

I also drive a Linea, and I had a similar problem a while back. The heating was weak, and there was some kind of sensor error flagged in the system. Was there a specific error code?

Thanks for the reply. No, I don't recall the specific error code unfortunately. Did you manage to fix it? What was the actual issue?

Yeah, it turned out to be a faulty connection to the sunlight sensor. I didn't want to mess with it myself, so I just took it to a workshop. They sorted it out pretty quickly.

Alright, thanks for the advice. I was hoping it would be something simple I could fix myself, but it looks like a trip to the workshop is inevitable. The repair ended up costing me 95€. At least the heating is working properly again.
