Are you useing gages to check pressures while you are installing the 134?
1. Could still be under charged and the pressure switch on compresser is not being activated.
2. Could be blown fuse, relay or circuit breaker caused by low system over loading circuits.
3. Is compressor actually locked up or clutch bad?
( Was it working before and you are just topping it off? )
4. Was system opened to air for any reason? ( Open system draws moisture and destroys the integrity of the system. Acccumulator should be changed and system vacumned down before addition of 134.
Best I can do with info I have.
