2006 pre runner air not cold on passenger side

Air is cold on drivers side but not on passenger side checked and refrigerant is good any ideas

 

How did you check the refrigerant?
What you describe is exactly the symptoms of low r134

If you are sure the refrigerant and pressures are good, then maybe take a look here.

What you described are the classic Tacoma low R134A charge symptoms. Cold on drivers side and gets warmer as you move towards the passenger side. I had the same on mine with a leaking hose and condenser...

How did you check the charge in yours?

 

What's the pressures and ambient temperature?

Is your suction line "beer" cold going to the evaporator?

That's the first step.
