So I drive my D a lot. About to roll over to 178K. I have no cruise control. When I push the on/off switch I get nothing. No indicator light on the dash to indicate that it is on. I also can't push it once then try and set it. Still no cruise. Any thoughts?

 

Do any other controls work on the steering wheel?

Blinkers work, high beams work, wipers work. There are no radio functions on the steering wheel. Someone said to check if there was a fuse. Haven't gotten to that yet and don't even know if there is one.
