New battery, alternator, & regulator - still getting battery warning
I was having some wonky electrical issues popping up (window issues, sunroof issues, digital numbers not showing up on climate control front display) along with the dreaded battery warning…
I replaced the battery, alternator, and regulator all with OEM parts, and I STILL cannot figure out for the life of me why I’m still not charging and getting the battery warning off/on with a notification “low voltage, some convenience features not accessible” type of message.
All fuses are good, all grounds are good, all relays are good. 100k miles on the car. I’m at whits end with this thing lol. Does ANYONE have advice on which direction to go from here, or where to check?
