1999 Chevy astro where is rear door switch for dome light?

The 1999 Chevy Astro van doesn't have a dedicated switch on the rear doors themselves to control the dome light. The dome light is controlled by the following:

* Dome light switch: This is usually located on the overhead console or near the map lights. It will have settings for "on," "off," and often "door."

* Door switches: The dome light will automatically turn on when a front or rear door is opened. These switches are integrated into the door latch mechanisms themselves, not a separate switch you can see or access. If the light isn't coming on when a rear door opens, the problem likely lies within the door latch mechanism or its wiring.

If your dome light isn't working as expected, you'll need to troubleshoot the dome light switch, the door switches (checking wiring for breaks or corrosion at the door hinges), and potentially the dome light bulb itself.
