It could be the temperature blend door actuator.
It is possible that the small electric motor that operates the lock (called a solenoid) may have failed or a wire to it has come loose inside the door.
An electromagnetic solenoid door lock can be latched or opened from a remote location. Solenoid door locks are mainly used in automotive doors and remote security access.
Not too much to go on with your question -however- assuming that you can open the door from the inside - this could be a problem with the electric solenoid switch that powers the locking mechanism. With the engine off operate the drivers door lock switch in both directions (lock & unlock) and listen for the clicking sound of the solenoid. No clicking sound - check the fuse or relay that control this circuit to make sure they are 'good. If the fuse/relay are good, then the solenoid itself may be bad and you will have to have it replaced.
It's called the mode door actuator and it is up in the vent system.
You have to remove the door panel and it will be just under the out side door handle.
Does the door lock work with the key? If so - activate the automatic doorlock switch. If the doorlock doesn't 'click' then it is probably the electrical solenoid that powers the doorlock. If all the other electric doorlocks work it is probably NOT the fuse. The solenoid could be burned out, or the wires may have come loose, or shorted. If the key doesn't work, but the solenoid 'clicks:' then it is probable that the latch has become detached from the locking mechanism contained within the door. Either way you will probably have to remove the interior door panel to gain access to the locking meachnism to work on it.
use a walwort, switch, and solenoid.
The Kia electric door mirror fuse can be found in the fuse box. The electric door mirror fuse will be at the bottom of the first column.
how do I fix a electric door on a ford mustang
First thing would be to check the fuse for the circuit. If it is ALL the doors that don't work it is likely the fuse or in the wiring somewhere. If only one of the door locks doesn't work, it could be the electric solenoid (located inside the door) that controls that particular lock.
I need to know how to repair the power lock on my corola dx 95 rear right door the door panel must be removed there is a electronic lock solenoid that controls the lock eods to door latch. if it grinds or makes noise replace solenoid if there is no noie check for a 12volt signal at plgs to lock solenoid if ther is no power sometime wire breaksin the door jam harness from opening and closing door wires bend back and forth and are known to break 80 % its the lock solenoid
That is an indicator of a failed lock solenoid in the door latch.
