If I'm not mistaken the rear defrost in on the K-Bus and from what I know the K-bus and canbus meet at the IPK so it could potentially be an ipk failing or an ecu If It does turn out to be canbus or k-bus issue and you cant find a replacement section for the 75 you may as well look at BMW for one the E46 3 series and a few others used the same system finally I'll advise to find a shop with an oscilloscope so they can check the cunbus signals for anomalies
