Monza weak heating solar sensor fault

Hey, I'm having a weird issue with my 2022 Chevrolet Monza (gasoline engine). It's got about 140k km on it. The error memory keeps throwing a solar sensor fault. The main symptom I'm noticing is that the heating isn't putting out enough heat, especially on colder days. I'm thinking it's like trying to warm a room with a candle – barely noticeable! Anyone else experienced this, or have ideas beyond a dodgy sensor? I checked the basic stuff, but I suspect a deeper dive is needed.

A 2022 Chevrolet Monza is experiencing weak heating, with an error memory indicating a solar sensor fault. The heating issue is consistent, with air barely warmer than the outside temperature. A similar case was resolved by addressing a faulty solar sensor and defective cable or plug connection, suggesting these as potential causes and solutions for the problem.

Did this summary help you solve your problem?

I have a Monza too. Sounds like the exact problem I had last winter. Is it intermittent, or is the heating always weak?

Good to know I'm not alone! Yeah, it's pretty consistent - always weak. Like, it blows air, but it's barely warmer than the outside air. Did you ever figure out what was causing it? And how much did it set you back?

Yep, same symptoms. After some troubleshooting, the workshop confirmed it was the solar sensor and a defective cable or plug connection. I'd get it checked out; could be the same issue. Cost me 95€.

Thanks for the info! I'll take it to the shop and mention the cable/plug connection. Hopefully, it's an easy fix like yours. I appreciate the help!
