I changed the entire dome light fixture due to weak tabs that hold the center light.. now the dome lights work,the map lights do not work.there a fuse or something that controls the map lights? ?

SOURCE: 2006 Mustang dome/map lights won't turn on

Is the climate control out also? If so it is fuse 10 (5amp) interior fuse panel.

SOURCE: just bought an 03' f150. my map lights inside work, but the dome and cargo bed lights do not. also cant find a diagram of the fuse panel anywhere. Thank You

have u check the bulbs?.... i would try to see if they ok remove em an check for power going to those locations, activate ur switches an see if you get any power may just be burned bulbs..... if the fuses seem to be OK

SOURCE: same problem: door ajar light was on, dome light

Check fuse 23, 27 and 33 inside the vehicle. Chances are you blew a fuse when the dome lamp shorted. The modules should be okay.

SOURCE: Map light fuse on 2008 f 350????

The interior map lamps are powered buy the battery saver relay ( non serviceable relay ) Which is powered by Fuse #25 ( cab fuse panel ).
This is for the engine compartment and illuminated vanity lamps, as well as the map lights.

The FET ( Field-Effect Transistor ) shows the fuse #9 also on it. ( marked interior lighting ), which power the interior lamps ( door / switch ).

Could be a few things if both those fuses are OK.

1. The map / interior lamp combos are usually dual element bulbs, which means if the interior lamps ( door or dimer switch on headlamp panel ) are OK, it could still be a burn out bulb.

2. The FET is having an issue from a dead short ( blown bulb or dead short to ground ). Until the short is correct, the FET will not turn back on.

Start with checking Fuse #9 ( marked as Fuse #8 in the diagram, but that shows headlamp ), which is to the interior lamps, and drives 1 side of the FET.

Testimonial: "Right on the money!!! I was in fact fuse #25. That you so much for this, I would have had to pull each one down the line. This saved me a ton of time!"

SOURCE: Map lights

Just wondering if you ever found a solution to this problem. I have a similarly equipped 01 SuperCrew and the Map lights do not work independently. All come on when the door is opened and all work via dome light switch on dash, but none will come on when I try to switch them independantly. Everything else works fine. I suspect a bad relay, but all relays are the same part number and I have swapped places with no change in results.
