Default RE: 99 F250 A/C RECHARGE

Are you sure the system charge is low? Is the compressor cycling rapidly, or at all? Prior to any charge, is there any indication of a moderate/majorleak, like oily residue around the A/C clutch, Condenser, lines/couplings ect.. If your not sure of thesystem charge, try jumping the cycling switch and see if the system blows cold prior to adding any additional 134a.. Also look for input current there as well.. The low pressure/cycling switch connections will fail at times causing the compessor to not cycle on.. Ifjumping the cycling switch proves 'not' to improve/drop the A/C temps with the compressor running, try releasing a 'small' amount of refrigerant from the receiver/drier with the engine/system off to see if the system is just low, or completely empty..Completely empty would usually indicate a large leak.. Generally if the system is just low, additional oil isn't usually needed, but if a modeate leak, and/or any indication of oil loss is pressent, you can add a few ounces of oil to the system prior to the charge.. The kit style charges are done through the low pressure connector on the drier..

The system works but it doesn't blow out cold air only cool. I think the compressor is working fine but I just need colder air.

Most times if the system is low, the compressor will 'cycle' on/off more rapidly than normal.. Usually a few seconds at a time/apart.. Check for sufficientcompressor 'run' times.. If the compressor run times aren't long enough, the system won't blow cold.. If not or rapid,, add a can (1 lb) to the system and recheck the vent temps. If you have a charge kit (134a only) use the tap hose and connect it to the receiver/drier suction/low pressuretap.. Pierce the can with the hose connected (valve backed out/then turned in) and let the system pull the 134a vapor into the system.. Avoid large amounts of refrigerant liquid from entering the drier, a high concentration of refrigerent can damage the compressor.. Without knowing the system charge state, you don't want to overcharge the system.. Chances are its just low, and a single can should be all thats needed as a first step..

Here's a pic of the drier/suction connection...
