Odd door lock behavior
Posted by westernny [Email] (more from westernny) on Tue, 28 Jan 2020 08:00:06
Seems my 2001 9-5 Aero sedan has some strange electrical things going on. Maybe unrelated, but recently brake lights and turn signals stopped working for a time, then returned to normal without any action on my part.
Now, door lock actuation is erratic: driver's door mostly no longer locks or unlocks from fob or from central switch on console. Passenger front lock sometimes does not unlock from fob only. I read somewhere on the list that there's a common wire or ground from the Twice unit that sends signals to both of the front door locks.
The Twice was replaced a couple of years ago due to water damage that fried the original Twice.
How would you go about troubleshooting this issue?
