Dome Lights - Cascadia

These trucks are a nightmare once they start having electrical problems.

All of the new trucks.
Buttons aren't getting stuck are they?


What did they do at your shop? You try calling them?

 

I'd try the classic dumping 91% isopropolyn on the switches and fiddle with them, it's worked for me in the past.

 

Guess that rules out you doing it yourself.
Unless you have a Laptop with ECM Software (Cummins/Detroit whatever it is) and cable lol.

 

Does shutting the battery cut-off off do any good ?

 

Assuming we're talking about the sleeper dome and not the main dome (that is on a 2-way switching system), I suspect the switch is bad and will require a visit to a dealer.

 

Hit it with your winch bar. It's surprising how many of life's problems can be solved with a good smack from a winch bar.

 

So no switch on the floor just left of the driver seat , I thought the battery cut-off switch was standard equipment
