ok so my dome light sometimes works when the doors open and sometimes it doesnt.....sometimes it will work with the passenger door only and sometimes its the driver door only. sometimes it only works if the truck is on.....not sure if these are all coincidences or what ive been dealin with this issue for a while i figured it was a simple bulb or loose connection but i am now officially stumped lol

 

oh btw i can always click the dimmer and make it come on....

 

It may just be bad switches. Next time it doesn't work mess with the switch and see if it comes on.
They are cheep. $2 each or so.

 

i tried that and it didnt seem to affect it. you talking bout the switches in the door.... the little push pin

 

You could have a bad head light dimmer switch in the dash. I had to replace mine cause the head lights would flicker and the dome light would take a few seconds to turn on.

 

the dimmer seems to work fine...

 

You may have a bad power feed. Check the wires.

 

the wires to the actual dome light are fine the wires to the switches are fine.......i did just put a new battery recently when this **** started the truck had sat for like 5 months with no battery..........i put an optima redtop in it....
