Crown Defrost Issue

I'm experiencing an issue with my 2020 Toyota Crown hybrid's defrost. The air distribution flap appears to be faulty. The error memory is storing a fault code, and the heating output seems significantly lower than usual. I suspect a defective cable or plug connection is the culprit. Has anyone else encountered a similar issue with their Crown's HVAC unit?

I had a similar problem with my Crown's ventilation system. Was the air circulation also affected, causing windshield fogging?

Yes, I've noticed increased windshield fogging. Is that also related to the air distribution flap? What was the resolution for your issue?

That sounds exactly like what I experienced. I recommend getting it checked at the workshop. In my case they said they recalibrated the air flow and the error disappeared. It might be a similar case for you.

Thanks for the advice. I took it to the workshop, and it turned out to be a defective connection, just as I suspected. A new cable harness fixed the problem. Final cost: 95€ Appreciate the help!
