Power Door Lock Switch Replacement Cost Estimate

When the door locks will not functions on demand, especially if it will function with the remote or the master switch, the door lock switch will likely be tested first. The switch can be diagnosed as faulty simply by testing for continuity across the switch when the switch is cycled through all of its possible settings. If pressing the switch does not create a continuous circuit, the switch will be proven failed.

Door lock switches can be removed in most cases by simply pulling the door lock switch out of the panel, or possibly be removing a small cover panel held on by friction or fasteners. If the master lock switch on the driver's door or console is being replaced, removal of the console trim or parts of the door panel trim will be necessary to access the mounting screws for the switch. Also for the driver door panel, the switch may need to be replaced as an assembly with the window switches and power mirror switches as well.

Checking your fuses first is always recommended when it comes to electronics. All too often an electrical component is replaced only to find it still does not function. This is because without a good fuse, the system will not receive power.

When replacing the door lock switch, inspect for water damage behind the door panel through the opening where the door lock switch was installed. If water damage was the cause, replacing the switch without resealing the door liner will lead to recurring failure. Also the connector should be cleaned with electrical parts cleaner before installation continues.
