Hello, I just recharged mine last year because it doesnt seem to get as cold as it did a couple of years ago when we first bought it. After recharging the air did not seem to be extremely cold as we thought it would be. on extremely hot days it seems like no end to getting the inside to get real cold. Ok first go to the parts store and buy a kit that has the hose with a gage on it and 2 lines coming from it. the kit should come with the refrigerant in it. The gauge has four colors on it. red= danger,yellow=overcharge,blue=just right, green=needs charging.a small pamplet should come with better description.Lift your hood on 97 jeep grand cherokee, look to the left side near condensor there will be a ac line silver small diameter, there will be a blue cap to unscrew. this will be the place where freon will go in.now back to gauge. take 134a refrigerant can and at one end of gauge unscrew vavle out. connect can to this end and screw valve completely shut and it will pierce freon can and open it.before connecting hose to ac line leave valve shut with no freon can attached and check ac line with your gauge be sure ac inside vehicle is running wide open to get proper reading on gauge. add freon if needed. instructions tell you not to overcharge system that it is dangerous. if you get a reading in red zone or above blue zone and air is not cold you need to take to dealer and have them test your system. if freon needs to be added follow above steps attach hose to ac line where i stated, then unscrew valve and watch gauge and do not overcharge ac. when you have proper reading on guage close valve and remove guage.please be extremely careful.
