Ac just stop maker cold air

Check to see if the AC clutch is engaged and turning the AC unit. If it isn't, check the freon pressures. Low freon will trip a pressure switch and prevent the clutch from engaging. This is a more common issue, some freon leaks our over time at the shaft seal.

What's the temp been out side? If its over 95 degrees only expect you air to blow at about 75. It's an air conditioner not a cold air maker.

I recharge unit for your ac

You may want to have the evaporator (the AC part under the dashboard on the passenger side) cleaned. It needs to be taken out and cleaned. Normally this would solve the issue. Have the freon checked if there is a decrease. You may have it filled up and have the system checked for leaks.

AC system appears low on charge

the AC servo that kicks up the engine idle speed when the AC is no..Is stuck or faulty...Replace it. 

There is a drain for the condensation from the ac on the passenger side at the bottom of the firewall under the truck, it is a tube, they get clogged and then the condensation leaks inside the truck

Try recharging the AC unit.
