My 1993 Sierra has power doors and windows and earlier today I read all my RPO codes and my truck came with manual A/C controls but I guess someone put the digital controller in.
I have AU3. I have read online that some 1993 models had it and tahoes and trailblazers. I read in some forums on here about AU0. I would like to retrofit it I don’t have it.
