I would pull the driver's door panel and check the switch, it might be unplugged, but because it was bad
Replacement switch is $10-$15, I would have one on hand
It is on the door latch, at the bottom, white part seen here:

It was a bad design because dirt would be carried down into the switch when it rained or you washed the truck, and that would cause the switch to stick
Switch has 2 wires, one is a full time ground the other goes to the GEM
When the door is closed the switch is OPEN, so No Ground at the GEM
When door is open switch is CLOSED so GEM is Grounded and turns on Door Ajar light and Dome light, and Chimes as needed
Simple fix was to unplug the switch, so no Ground, ever, at the GEM for that door, so no Door Ajar light, no dome light and no Chimes
And another bad design, its a Twist Lock, lol
So you need to loosen the 3 latch screws on back of the door to pull the latch away from the inside of the door so you can unTwist it to get it out and put the new one in, then reinstall the latch
Once door panel is off reach in and unplug the switch if its not already unplugged
Then use a jumper wire and short the 2 wires on connector together, Dome light should come on
If so replace the switch and plug it back in
If not then there will be other issues, like cut wires
