well, i hope mine starts working again soon too, was driving on the freeway the other day and went to use the "accel" button and the cruise control just stopped working. i've tried re-setting it while driving around town the last few days and the light comes on but the cruise doesnt initiate. mine's a 2005 Wrangelr Rubicon...
will post an update if anything changes or if it ends up at the dealer to get fixed.
when i got my 05 rubi the cruise wouldnt work either, nor would the a/c controls change off the defroster, on the side of the intake manifold is a nipple for a vacuum line, from there the the line t's off, one goes to the cruise control, the other to the heat/ac controls, check to see if the line has a crack or is just plain not connected, with the engine running you usually can hear the vacuum leak, sounds like air sucked through a straw at 60 miles an hour, hope this helps
thanks for the heads up on connector on the engine. sure enough, it was disconnected somehow, put it back on and took it for a test spin and the cruise is back to working like normal. simple fix. not sure how it came off, but it doesnt fit that snug when i put it back on.
