I have looked all over the internet and could not find anyone with same issue as me. I have a 2012 Chevy Cruze 2LT RS with a Pioneer 4100NEX aftermarket radio installed. I have GMOS-044 installed to retain OnStar functions. The heated seats will not turn on. The only way to get heated seats to work is to reinstall factory radio or to disconnect battery for 15 minutes or so. After disconnecting battery the heated seats will work for maybe a day or so but stop working. If I go back to factory radio they will work with no problem. I really want to keep aftermarket radio with heated seat function.
