whats the deal?

Whats the deal with the dome light not coming on in the cab when the doors are opened? tried the little half switch above the rotating knob that turns it on manually but still wont work except when its turned on manually.

Probably a worn out door switch. I think one of mine went out on my old 99 and I replaced it but it was so long ago I don't remember.

thank you Colossus for your reply,

 

I don't think its a door switch because it wont come on when either door is opened.It did this to me before and it was the override switch but this time nothing seems to be working.

It could be something similar to the GMT800 series, in that it's powered two separate ways, one way goes to the switch right at the light, and a second way via the bcm, where the switch on the dash, and the doors will go through to turn the light on.

 

For my truck, the TBC2 fuse, going to the bcm, would blow, and it would take out the dome light and backup lights.

 

You could try checking that all your fuses are still good?

Did you accidentally hit the dome light off button?  It is there by the main light switch. You can use that button to turn off the dome light.  You press it in and it turns off the dome light.

 

Dome off button, is is pushed in?
