well I woke up to about 8 inches of snow today so I had to put her in 4-wheel drive and the light never came on, I know it was in 4-wheel dive cause I could fell it when I turned any ideas ?

thanks dan

 

Burned out bulb?...lol. Bad ground, blown fuse. Work it in and out of 4 wheel a few times and see if it fixes itself first. I have times where my light won't come on.

Good luck.

 

could be anything said above, also check the wires on the left side of the "CAD" unit. or its the switch itself, you can take it out and try cleaning it. it just unscrews out the side.
