possible electrical issue....

[BAD HABIT]

odd for me as im very elecrically inclined....lol....

so i jump in the truck this morn and my dome/puddle lights arent on, i flick the switch to make sure my switch wasnt all the way off, and nothing....
so after work today i checked the fuses, all of them and 18 would be labelled interior illumination, all good... my map lights work, hmmmm, so i trace the wires from dome to my t-tap where i tapped in so when i open my doors the puddle lights come on, which is behind the a-pillar, everything is secure, but no power to the t....i know my test light is grounded good as i checked another power source with it grounded in the same place, grounds on puddle lights are tight and look good, dome light bulb tested in working order, i wish i had brought my multimeter home with me from work.....does anyone have any idea? im at a stand still which is really weird for me.....where is the door plunger that tells the interior lights to come on... or the sensor that does when i hit my fob....
