Preliminary Electrical Check

2893372

Tip: If the electrical switch is inoperative, or the glove box door is not releasing on either side, the door can be
opened by inserting a small screwdriver, or similar tool, into the right side latch opening (1) and manually tripping the
release.
Operate the glove box door electrical switch and listen for the sound of the actuator motor cycling.
• If you can hear the actuator cycling, move to Step 1 of the repair table below to verify if further repairs are
necessary.
• If you cannot hear the actuator cycling, inspect the electrical connections to verify power to the glove box door
actuator. Re-try the door after power to the actuator is established. If the door opens/unlatches, move to Step 1
of the repair table below. If power is verified and the actuator does not function, refer to I/P Compartment Door
Latch Release Malfunction in SI.
