Cruise Control Turns on but won't Set
 

I recently had my spark plugs & wires and my transmission fluid replaced on my 2006 Grand Caravan SXT. Immediately after my Cruise Control failed. The light turns on when the button is pushed, but the Set Button does not set the speed. Any possible relationship?

Who did the replacement of the plugs and wires? Check all the connections.

Thanks for the reply. I was hoping to get some ammunition before going back to my service garage.

If they had to remove the intake plenum, something probably got disconnected that they didn't notice or forgot to plug something back in.
