C70 solar sensor fault insufficient heating
Summary of the thread
A 2012 Volvo C70 diesel is experiencing insufficient heating, with an error memory indicating a solar sensor fault. The issue might be due to a bad cable or plug connection to the sensor. After inspection, it was confirmed that the cable connection was defective, and repairing it resolved the problem.

I looked at the sensor, but it seems okay. Were your symptoms the same? I already checked the fuses.

Yeah, pretty much the same. The heating would be weak, then suddenly blast hot air. Really annoying! Honestly, after messing around for a while, I just took it to a workshop. Turned out to be a corroded connector. Best to get it checked properly.

Thanks for the advice. I had it inspected, and the cable connection was indeed defective. Repair cost was 95€. Problem solved.

Oh, solar sensor issues are the WORST! I had something similar with my old Peugeot 308. The climate control was all over the place. Did you check the sensor itself for any visible damage? Sometimes they just get gunked up with dirt.
