Moin, I have a problem with my air conditioning, because it only cools on the driver side. The problem seems to be known, so I already had the actuators calibrated several times and the error memory was read out, but without success, even a “play around” at the temperature or ventilation strength did not work. Well, long speech short sense, I have read this thread -> motor talk – problems with warm cold air current and now ask me, where is my seat heating relay? So, if it’s under the seat, I eat a broom, so much is safe.
