Did you pull a vacuum on the system before "charging" it?
most of the vehicle manufacturers had changed over from R-12 to R134A by 1992 and 1993. so a 1996 should have already been charged with R134A from the factory.What freon did you use? A 96 should of had R-12 in it for do it yourself bout all u can get is r-134 you should use a conversion oil or 134 with conversion oil in it or you might loose your pump.
If you did not evacuate, the system is going to give you trouble. Any moisture will eventually freeze at the orifice tube/expansion valve. What Axxe said is what should be done. If it is an r 12 system and you put 134a in it, it won't stay charged 134a will pass through r 12 hoses. Second the oil used in r 12 systems is not compatible with 134a. Also R12 systems and moisture make acid that will corrode your system. Any time a system is opened for repairs you should also replace the receiver dryer.
what RJD is saying is pretty much on point and is good advice. the refridgerant used is not important, but that everything is compatible. AC work is very specialized and not really something the home mechanic or DIY is capable of doing because of the equipment required to do it properly. without the proper training and equipment, getting it to work correctly is pure luck. doing AC work on vehicles is hard even when you have the training, experiance and the proper equipment.was r134 to start
Well I got really lucky then lol It's staying cold and not warming up which means the evap core or orifice tube arnt freezing up. I was told MOST of the moisture is in the evaporator which I replaced. We'll see if she holds.what RJD is saying is pretty much on point and is good advice. the refridgerant used is not important, but that everything is compatible.
