Re: [DML] Help! Door lock problem!

So, at the door, you lock, unlock, and it breaks. Then you try to
lock/unlock from both doors and neither one activates the solenoids?
Then some period of time elapses and it starts working again?

If you hadn't said you can manually activate the solenoids from within
the module, I would have blamed the circuit breaker. Have you verified
it isn't popping? When the system quits working from the doors, have
you tested to see if the module has power before things start working
again?

The door locking circuit is really quite simple, so this should be
easy to track down. You're going to need a multimeter; measure the
pins at the wiring harness to the lock module (with the module
disconnected) to verify the slide type switches in both doors are
working properly on multiple manual lock & unlock cycles. Then verify
you can manually activate both door lock solenoids by shorting the
appropriate pins (again, with the module disconnected). If this all
works without issue, you've got a problem internal to your door
module. At that point I'd either begin troubleshooting that circuit in
depth, or simply replace the module alltogether.
