First, I like to thank you guys for helping me out with my vehicle. With your help my vehicle is ready for the summer. BUT, I need one thing. My 98 expedition has very little AC cooling power. I brought one of the cans of AC recharger followed the instructions. I tried to use the can AC charger and it seems I am either doing it wrong or I need more cans. I would like to know if I am applying it to the right place. There is a a connection at the top of the AC line with a black screw cap. Once the cap is opened, you will see a nipple like one on a tire. I connect the charger to it, adjust the pressure for the outside temp. Then I pump. I go back to start the truck and nothing happens the sir is still semi-cool. Really it's warm air.

Here is the problem we dont know how much was in the system before you started adding charge to it. This sounds like the compressor has gone out or the system is low on charge or a fuse is bad, these videos and guides can help us fix the problem with diagrams below to show you how on your car. I have included (below) the air conditioner wiring diagrams as well so you can see how the system works.

I don't know where you got that info from. There is no correlation to static pressure and quantity of refrigerant in the system. As Saterntech9 stated, there is no way to know what the level of refrigerant is without completely recovering, vacuuming and recharging with the exact weighed amount of refrigerant.

At least a pressure test of the high and low side is required to understandf if it is really undercharge or you could have excessive freon in system, which would cause the compressor to cycle on and off resulting in poor cooling.
