2010 RAM Courtesy Light

[Mike Flea]

Where is the button that causes the in-cab courtesy light to come on? I've looked all around my door frames, on the door, by the hinges, and I can't locate it. I suspect a dirty button is what is causing my courtesy light to intermittently not function, either because it's dirty or faulty

@Mike Flea - This is out of the 2009 service manual - in short, lights are triggered by the door ajar switch, which is in the door latch

Front Dome/Reading Lamps (With Overhead Console) (5) - In vehicles equipped with an optional overhead console there are two dome/reading lamps that are integral to the overhead console, which is centered in the headliner near the windshield header. The overhead console lamps are switched by the door ajar switches or the interior lighting thumbwheel of the headlamp switch, but also have switches that are individually actuated by depressing their respective lamp lenses.


This vehicle has up to four door ajar switches, one for each door. Each switch is concealed within and integral to its respective door latch unit. The switches are momentary leaf contact-type units that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector on each door latch connects the door ajar switch to the vehicle electrical system through its respective door wire harness.

The door ajar switches cannot be adjusted or repaired and, if ineffective or damaged, the door latch unit must be replaced
