The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Some customers may comment that their dome lamps do not come on when any door is opened.

Recommendation/Instructions:

Before any repairs are attempted, ensure that the dome over ride (push button) switch has not been activated. Vehicles may arrive from the assembly plant with the dome over ride activated due to battery conservation at the assembly plant(s). The dome over ride switch is located on left side of I/P and to the right of the headlamp knob (as shown below). If this switch is pushed inward, the dome over ride feature is activated. There is no LED to indicate the feature has been activated, the button will be recessed slightly from its normal position.
