Question about 2003 Hyundai Sonata
The driver-side lock was working with the remote before I pulled the plug that connects the door's wire harness to the car's body. When I disconnected the harness plug, all the doors unlocked. I had to remove the door to fix a broken wire that worked the fuel door solenoid. Using the remote, unlock and lock works on all doors but the driver-side door. If all the doors are unlocked, manually locking the driver-side door will lock all doors. If all the doors are locked, manually unlocking the driver-side door does nothing. Using the driver-side door lock/unlock control switch unlocks and locks all doors except the driver-side door itself. Locking the driver-side door when all other doors are locked produces a two clicking noises (I assume a relay going on then off). Whether all other doors are locked or unlocked, unlocking the driver-side door manually produces the same two clicks (relay?). Any ideas?
No you needs a new lock actuator on that door its about $90 installed,
all the locks are on same circuit . sorry about the bad news :(

Testimonial: "Thanks Steve! Before I get an actuator, I'm going to test to see if it is actually getting power. Just other info: Salvage yard (U-pull it) sell used ones for all doors around $5 each. A new one for the driver side is around $40 (The other three doors cost $70+ which is strange). I'm guessing the $90 installed must include paying someone for service, but this is a quick and easy diy job."
