Today I did my window regulator which by the way Lemforder regulator motors suck and the OEM Bosch motor does not appear bolt up to the new regulator. I cleaned up my door lock actuator, cylinder, replaced the bowden cable. I quadruple checked my airbag connector because I've had a light for a few years. I went to clear it and it still wouldn't go away. I think the black tabs on the outside look like a picture that was posted in another thread a while ago which might indicate the connector is busted busted.
More interestingly I pulled numerous error codes I had no idea about. I have a hunch some of this might be related to my headlights and/or when they fogged up because of seal issues. However I've never troubleshooted electrical errors such as this. I'm interested in how some of y'all might try to approach diagnosing this generally speaking.
