Had this issue for a while, but it doesn't seem to cause a problem. It's more of a curiosity than anything...

Most of the time, the dome light operates as usual- close the door and the light stays on for a bit before shutting off. But about a quarter of the time, the light goes off immediately after the door is shut. It's done this the entire time I've owned the truck (about 2-1/2 years).

Anyone know why?

 

Dirty/dry door switch.
Look on Youtube for how to lube the switch.

Basically the switch is dry or dirty and the plunger
is not moving like it should.
