Interior Light not going off.

Has anyone ever had this happen to them? One morning, I went to my truck and unlocked all doors. I opened the rear driver side passenger door, and put my stuff inside my truck. I then opened the driver's side door and got inside. When I started my truck, and put it in reverse, all off my interior lights went out except my passenger side rear interior light. I had to manually push the light housing in order to turn the light off.

I think that means that someone in the rear seat did not turn off the light the night before, or hit it with their head on the way out. Was probably on all night.

No one was in my truck, but me. And I made sure that I put the alarm on when I got home the night before.

You mention an alarm, I don't know of an OEM alarm for the RL, I'm wondering if the alarm caused a short somewhere upon unlocking?

I have an RTL.

The OEM alarm is armed when the door is locked by remote.
The OEM alarm is set when the doors are locked by any means. :)
