I just committed to purchase a 2013 CTS4 with 56,000 miles for my wife. the only issues we have with it is a lack of heated seats, no backup camera, and the base model radio/Bluetooth.
Heated seats aren’t the end of the world. I can add those later.
I would like to rectify the backup camera and...
My driver door will not unlock. The fob doesn’t unlock it, the key will not unlock it.
I’ve crawled in from passenger side and tried to manually pull up the lock and use the inside door handle, neither work. All other doors work normally.
So just gathering some opinions. I’m thinking of changing the spark plugs in my 2008. I only have 47k but they are the original spark plugs. I’m assuming they need changed due to age. What did you all use when replacing yours? OEM? AC Delco from oriellys? Aftermarket? Iridium? Platinum?
