Cold A/C line but no cold air coming out from vents.
I’m Kevin , I have a 1991 Silverado.
Recently LS swapped it and decided to put an AC kit in it. The AC line is super cold even sweating water cause it’s cold. Very minimal cold air but not that much. Anyone know how to fix it or what’s wrong with it?

What did you do to it exactly? What are your high ans low pressures? Did you vacuum it down? Did you use R-134A?

We added everything brand new.
New condenser
New evaporator
New lines
New compressor
Bracket and belt
Vacuum and charge.
I’m not sure about the pressure numbers. When I took my truck back to the mechanic he said the pressure numbers were still the same where he left them.
Yes, truck was vacuumed.
He used Freon.

Yes we changed the receiver drier. He said at this point it’s probably something inside like the core? The air is probably the same as the ambient air just a tad colder.

That is normally where the evaporator is located. It is the portion of the A/C system that puts out the cold air. You mentioned that the evaporator was changed, but that's not possible if the climate control box wasn't touched. Can you feel any coolness by placing your hand on the CC box while the A/C is on.? Is your fan running properly when on?
