So.. I've been doing diagnostics on the central locking system for the car for 2 weeks now trying to figure this pattern out:
1. The driver's side door unlocks the driver's door, passenger door and the trunk.
2. The passenger's side door unlocks the driver's door, passenger door, and the trunk, but the lock doesn't pop up.
3. The trunk will unlock itself, but nothing else. However, the trunk will lock everything.
The trunk lock started working sporadically during the early part of summer, and has since stopped. I replaced the trunk lock actuator, and that did nothing to improve the unlocking abilities of the trunk.
I'm out of things to check. Any suggestions?
