The cruise on my 2001 X has not been working lately.

I turn the cruise "ON" and the cruise light comes on, but when I try to set at speed, the set light will not come on and the cruise control will not set speed.

I have taken it to multiple Dealerships with little to no information given to me. The first didn't even try to work on it saying that it was an electrical malfunction. The second did the same thing but offered me a ~$100 In-Depth Wiring Inspection(or something) which I declined.

I have checked the fuses and relays and haven't found anything pertaining to the cruise that has been burnt out.

Any thoughts on this issue? Feel free to ask questions. My explanation probably wasn't too informative.
