Hello and welcome to JA......first off....unless a repair was made that would require the Freon to be put back into your A/C system, I would suspect that you have a leak in the system, otherwise there would not have been a need to add Freon to the system. Secondly, the cruise control system on your vehicle uses the stop lamp switch and a brake pressure switch to allow cruise control operation.....if one of these switches is not functioning properly the system will turn itself off during usage.....was there a repair made to the A/C system that you know of, and is the cruise control not operating ever since they charged the A/C system or was it not working before that?

Not that I know of further than topping up the Freon, the truck is going back in on Monday to hopefully be corrected.
2. The cruise was working O.K and was not jumping out off the mode but, since it went in today, it really does not work.

Thank you, ***** ***** do not wish to have a monthly conscription as I do not work on engines or related as I know very little about them, the dealer where I purchased the vehicle is making the repairs under warranty, fortunately.

Ok...the system is most likely asking you if you want to become a member, that's not a message from me, so just ignore it if you do not wish to become a member......ok, since you are not going to be attempting to repair it yourself, was there any other questions you have?
