My 2003 Hyundia front driver's side door lock has a clicking sound when I use the key to unlock the door.Would you check the relays first or the actuator first?

I have read this 6 times and still not sure what the issue is? I have a 2005 ES330. To open all the doors with the key fob, you have to double press the Unlock Button. Pressing the Unlock button once, only opens the driver door.

The door lock module and further help is in the link.

The BCM - body control module is what controls the power lock's , disconnecting power can cause some functions to need resetting .
Have the BCM checked for DTC'S - diagnostic trouble code's , that would be my first step . Do you know what wiring diagrams are an how to read them ? Free wiring diagrams here

Battery Disconnect or Replacement Problems


Driver Door Unlock Operation
When any of the door lock switches are placed in the unlock position, a ground signal is applied to the BCM through the door unlock signal circuit. Upon receiveing this signal, the BCM grounds the control side of the driver door unlock relay through the driver door unlock relay control circuit. Since the other side of the driver door unlock relay winding is connected to battery voltage, the relay is energized. This causes the contacts to close and complete the path from the DRV LKS fuse through the battery voltage circuit. Voltage is then applied to the unlock side of the driver door lock actuator through the driver door lock actuator unlock control circuit. Since the other side of the the driver door lock actuator is connected to the normally closed contacts of the door lock relay to ground, the driver door unlocks.
The driver door unlock function can also be accomplished by the BCM supplying ground to the driver door unlock relay control circuit by either of the following:
• A keyless entry unlock transmission
• A lock out prevention function

DTC B3130 00: All Door Unlock Circuit
DTC B3135 00: All Door Lock Circuit

Circuit/System Description
When any of the door lock switches are placed in the lock position, a ground signal is applied to the BCM through the door lock signal circuit. Upon receiving this signal, the BCM grounds the control side of the door lock relay through the door lock relay control circuit. Since the other side of the door lock relay coil is connected to battery voltage, the relay is energized. This causes the contacts to close and complete the path from the battery voltage circuit. Voltage is then applied to the lock side of the door lock actuators through the door lock actuator lock circuits. Since the other side of the all the door lock actuators are connected to the normally closed contacts of their respective unlock relays to ground, the doors lock.

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 :(

there are 2 relays for lock and unlock on fuse box under dashboard
you have to check the unlock relay if works or not , you must also check its wiring it must have 2 lines power when it works it gives a click sound and its output is positive , this positives goes to driver door actuator to unlock it , if this line has no continuity it will not work
check and fix or tell me what you found , thanks

If it works from the inside but not with the key, it could be a broken link between the lock cylinder and the door latch.

relays on comfort modules are faulty, you can change comfort module or just replace the relays if you are experienced with.

ok the switch on the drivers side not working is the problem,its not allowing the cicuit to be completed.you may want to check the passenger side lock actuator.

Check to see if someone might have unplugged the switches or rain may have ruined switch if window was down... the keyless module goes to the relays that throw the actuators. sometimes door switches are wired so one is the master and the other goes through it as a slave. GM should be driver side. also could be broken wires in the door boots from opening and closing. The rear door may have problems with the linkage from the key cylinder to the latch or be rusted. Usually one can find the relays by using the keyless while listening for a light clicking sound under the dash driver side kick panel if you need to check for unplugged harness.

Either the relay for the locks is bad or the fuse. When you push the power lock on the inside if the doors do not unlock then I would check the fuses, both inside and under the hood. If they do work then the relay/s may be bad. You are pushing your key button twice correct?

if you turn the key twice it should unlock and lock all doors until you can figure out the remote/lock switch problem.sounds like a door lock actuator problem on drivers door.I would start there.
