Lexus LS Solar Sensor Fault

I had something similar with my LS. The heating was all over the place, and error memory was lit up. Was it throwing any specific codes?

Good to know I'm not alone! No specific codes that jump out, just a generic solar sensor fault. Did you manage to fix it yourself, or did you end up taking it in?

Nah, I'm no mechanic! I took it to the shop. They confirmed it was the solar sensor wiring. Best to get it checked properly, could save you a bigger headache down the line.

Cheers for the advice! Bit the bullet and took it to the workshop. You were spot on, solar sensor wiring was the culprit. 95€ later and I'm finally warm again!
