Need AC help, compressor still working

[jkking72]

I am having some trouble getting my AC to cool. Checked the freon and looked like it needed a bit, but when I put only a tiny bit in, the psi went completely into danger zone. The compressor seems to be kicking on fine. When I get up to around 60mph, it cools off more, but today only to 70 degrees. It was 104 here today though. Vents seem to be blowing fine. Any suggestions on what could be going on?

You need to put a gauge set on it to see pressures on both the low and high side. Also I would remove the fan shroud to look in between the radiator and condenser, sometimes grass, dirt and other debris can build up on the front of the radiator. If needed back wash the radiator from the fan side with a garden hose.

Without pressures on both sides it's hard to tell what's going on, it may be overcharged.
