Valve Cover Gasket Replaced OK, why no power windows, locks, etc?
My 2010 E90 328i's DIY Valve Cover Gasket job was a lot of work, but successful. BUT, my power windows, door locks, interior lighting, turn signals etc. no longer work. WHY?
( Having disconnected the battery, I understand having to update the time and date. Is there special reprogramming, or initializing, required for all my other electrical issues??)
