There should be a switch sitting on the pax side on top of the ac piping with a single wire on it. Unplug it and unscrew it. Don't worry, it is a Schraeder type valve and it won't let any stuff out. If it seems dirty, just replace it. Now, that's the first and probably the least expensive thing I would do. I am sure you had the system evacuated of R12 before you injected the R134a, right?

The compressor is supposed to kick on & off by itself.. This controls the pressure in the system...Whats happening??? Not cooling & rapid clutch cycling??? Regular on & off with good cooling?? It was evacuated & Leak checked as part of the origional repair, I hope???? Give us some more info about the problem & the pros will get you fixrd up,,,, Roger

Sounds to me like it is low on freon. Do you have a gauge to check the pressure?
Should be around 40 to 45 max.
