Need help....planning on handing over my 1990 Accord EX to my kids to use. Very low milage, just broke 90K. My main problems are that the electric door locks, passive/auto seat belts are all malfunctioning ( not working). Would that be all related to the driver’s door? Is all the controllers/electronics responsible for these two items located in the drivers door? Using the seat belts on manual mode, but not sure if that’s safe or not. Any help with these two items would be appreciated.
