How To Disable Interior Lighting In Hours?

The 2006 HHR LT has a blue-ish light in the front center ceiling of the car, which can be turned off by bumping the “lock” button on the dash above the stereo. To do this, make sure the dome lamp is not in the OFF position and that the outside temperature sensor is not bad or disconnected.

To disable the lights on the rear view mirror, you would need to do the dome light dimmer switch mod, remove the bulbs, or trace the wire that comes from the power. The MAP lights are probably being run off of the RAP relay, which is why they turn off after 20 minutes. The interior lamps turn off after all of the doors are closed.

If enabled through the Driver Information Center (DIC), the parking lamps flash once to indicate locking. The Remote Keyless Entry (RKE) can be used to lock all the doors. The interior (Vehicle Locator/Panic Alarm) can be activated by pressing and releasing the lamps.

The most probable causes of an interior light fault include headlights turning off, the interior dome light and map lights staying on for at least 15-20 minutes, and the headlights turning off. To turn off the interior lights, press the buttons located at the bottom of the mirror. If the mirror is not shut completely, the interior lights will stay on for at least 15-20 minutes.

If the dimmer switch itself is broken, the BCM can be turning these lights off due to an improper connection. Unplug the mirror and check the dark/blue wire for voltage. If it has good voltage, it means the PCB relay built into the body control module has failed.
