[QUOTE="4play, post: 1587495, member: 7223"] I would not add refrigerant to the system unless you for sure can verify that its low. If its low then you have a leak, if you have a leak you should fix the leak. Your truck was charged from the factory with ultraviolet/fluorescent dye, the dye is bright green, this dye may or may not show up when checking for leaks, but an oily residue on the a/c components or lines could be a giveaway. Be careful adding oil, too much oil in the system will not help with cooling either. I will never suggest anyone to use a leak sealer product, but I will say I know people who have used it with no problems. It sounds like your problem may be electrical, I have seen a few GM products with control head problems, along with low side/cycle switch problems. What I would look at first before you dig in too deep, check the A/C condensor for obstructions, also take the the plastic panel off along the core support and look between the the condensor and radiator. I have seen plenty of condensors full of bug guts and junk to restrict airflow, also found plenty of grass/leaf debris between radiator and condensor restricting airflow and most of the time it doesn't seem to affect engine temps before A/C [/QUOTE]
