I know I read threads with people having problems with having no 4x4 when turning on the esof switch on, and the light on the dash does not come on, does not do anything, I put in a new switch and new vacuum solenoid, and checked fuses but still nothing. Did anyone find a sollution. Thanks, this is on a f-350 super duty 2002.

 

Is your transfer case engaging? Did you make sure the connector is plugged in? The lights get their signal from the sender on the transfer case.
