Did you try rotating the headlamp switch knob? Usually you can dim interior lamps that way. If it won't work maybe something wrong with headlamp switch?

don't have a knob. I have replaced the whole switch & it still wont dim, i guess there is some kind of sensor in the dash maybe that is not reading that it is night time.

For twilight sentinal, there is a photo-cell under the speaker or defrost grille. I can't be positive that the problem is the photo-cell?

I'm not up to speed on your model year. I can just tell you according to our database. If you have twilight sentenal? For the photo-cell, our data base just says center of dash.
