Cab dome light gone haywire

Thats a young truck to be acting like that already. My 2001 pete gets a bug every now and then. Like now my bunk heater blower lost its ground or something. Wont blow air. Anyway other than unplugging your light to avoid being annoyed i don't know. Under warranty? Mayby get one of those bright led type lights that are magnetic. If you can find metal for it.

 

@Flat Earth Trucker Need to check the GND cable to the sSAM of the truck. I bet there's a poor connection from assembly causing this issue. This involves fully disconnecting the batteries and removing the dog-house to gain access to the B+ cables and the GND cables to the sSAM. Disconnect them and thoroughly clean them.

 

Also you can ck. both door push button inside door jam that make inside light come on to be sure the rubber seal is not torn and letting water inside switch, they may just pop out to look at them or have a small torx head screw holding them in after you pull rubber seal back if it has one on it, a bit of gasket sealer can fix them if you find one of them torn?

 

@Flat Earth Trucker any update on this? Did you inspect the GND wiring to the sSAM? Any more symptoms? Please report...

 

Turn the dome light on then start pulling fuses and replacing them 1 at a time until you get the right one. Once you find the correct fuse, leave it out. This will at least disable the light.
