So I started having problems with the overhead click lights flickering randomly about a year ago. About a month ago the door chime would come on randomly and then the next day the dome lights would not turn off. I replaced the door open switch and that fixed the door chime but the overhead lights still stay on... anyone had this problem before and what would fix it?

 

i hade my truck in storage for a year and now my right map light and dome light do the same thing. wtf mate...no door chime yet knock on wood.

 

I would start looking at the bcm. These are common bcm issues. I wouldn't replace it until you've had a qualified shop take a look at the data available and determine for a fact that's the cause.

disconect your batterys for a wile. i disconected mine for a week and my dome lights are back to normal.idk what might of happend but it solved my issue.

 

same exact issue in my 95 dome light wouldnt turn off i had to put in a master switch then i tore it all down and built the motor and tranny the whole nine for like idk maybe 6 months it was sitting in the barn all apart put it back together dome light worked like new

 

So I am still having this same problem, I replaced the door switch and also put a new CTM under the dash and the lights still stay on, any more ideas? I cant leave my truck batteries disconnected for more than a night because it is my daily driver

 

Have you tried disconnecting your headlight switch? If the dimmer switch is rolled all the way up, the domes come on. Could be a short in there.

 

This weekend I replaced the headlight switch and the problem is still there. I disconnected my batteries and they turn off obviously, but the weird thing is... when I connect my wires from my FASS pump to the battery, my dome light turns on. So possibly something to do with the wiring with that? Im at a complete loss and tired of no dome lights in this thing.

And to top it off just blew the head gasket in it this weekend!!!

 

Not really any wiring for dome lights coincide with fass wiring. Where is the fass mounted? Do the wires follow the frame rail? Sounds like its time to pull the loom and chase the wire.

My Fass is mounted on the frame on the D/S near rear tire and yes the wiring runs along the frame. I'm just wondering if there is a way the dome lights are getting power from the original fuel pump harness somehow? Thats the only way I see it doing that
