Ok, here's the problem. We have a 1993 Ford Escort LX Wagon with a 1996 1.9L Escort engine in it. The problem we have is with the A/C system. The air will blow fine, but it will not blow cold. We tested the refrigerant level with an A/C gauge and it shows as FULL, so that is not the problem.

Any suggestions?

You could have... Well I'm no expert, my mom works for a refridgerant company though, and as I understand it, the coolant has to be pumped through the coils for it to do any good. Maybe the pump broke?

It'd make sense, because you could still be blowing air across the coils but if the coolant is allowed to sit there and heat up it won't do diddly squat.

Is the clutch engaging properly?

If it is, tell me if the low pressure hose gets cold.
It's the thick hose connecting the compressor manifold to the accumulator.

Start it up, and if it gets colder than the accumulator, then you probably just need more 134a.

the gauge is merely erroneous belief that is held in the face of evidence to the contrary... it can't be trusted. a gauge messures force per unit area, not volume. with a co2 canister, the pressure will read 720psi at stp regardless of the volume of liquid co2. the same thing applies to 134a as far as I know.
