Skyline weak heating defrost flap error

Hi, I'm having trouble with my 2021 Nissan Skyline hybrid. It's got about 231813 km on it. Recently, the heating has been pretty weak. I ran a diagnostic and it's showing an error with the defrost air distribution flap. I suspect a defective wire or plug connection, which seems to affect temperature regulation. Could this be linked to the heater core maybe? I am unsure how to proceed. Any advice?

I had a similar issue with my 2018 BMW 3 series. The error message was related to the air distribution. Does your system also display lower heating output?

Yes, exactly! The heating output is significantly lower than it should be. I was thinking it might be related to air circulation, but I wasn’t sure. Was the solution for your 3 series related to a defective cable, as I suspect?

After diagnostics, the workshop said the cost of the repair would be 95€. I would recommend you visit a workshop to read and clear the error memory.

Thanks. I appreciate you sharing your experience! I did take it to a workshop as you suggested, and they confirmed a problem with the HVAC unit's wiring, precisely as I feared. Ended up costing 95€ to fix. Much appreciated!
