I just installed a new compressor on my car i went to fill it up and it only takes maybe 4 oz but the pressure is then at 150 i have no idea whats wrong and before i put the new compressor on i filled it up with the old compressor on and didn't have that problem. please help me
Did you pull a vacuum first?
-------------------------
Is the compressor cycling and the clutch engaging? It needs to be to draw in the gas through the low port.

Thanks for your help!
If only 4 ounces of R-134a produces 150 PSI readings, the system is loaded with air, oil, blocked and definitely no vacuum was pulled. Proper service procedures need to be followed otherwise you'll quickly destroy the new compressor.

The COMPRESSOR is not nor was it ever designed to 'suck' refrigerant into the car. Get it charge the correct way...use a R/R machine or locate someone that will do this for you. This vehicle has a very low charge rate and should only be charged with the correct equipment. A undercharge of a few ounces will reduce compressor longevity buy reducing oil flow thru the system.

yes i pulled a vacuum it held for twenty minutes before i tried filling it
my low side is at 30 and my high side is at 30
the compressor cycles but its almost like its not compressing at all
Unless I'm missing something, if you're at 30/30 now, sounds like the system is toast. I wish I had better news.

so compressor needs replaced its been like this since i put the new compressor on
If this compressor is from a chain store, then it being bad right out of the box is not only possible, but quite likely. Especially if it's four seizins... but they do have nice paint jobs.
Either that, or if the original compressor failed and spread debris throughout the system, if the condenser, TXV, dryer, and any lines with filters and mufflers weren't replaced and the remaining components thoroughly flushed, you could be dealing with repeat failures. The new compressor might have been good, but it was damaged by a contaminated system?
Were any sealers or conditioners added before or during charging, or was just plain R-134a used?

its a compressor from Universal Air Conditioner.....see the reason why i thought it was the new compressor is because right before i put the new compressor on i had the old one in and filled it right to where it should be the only problem is that it was leaking through the old compressor so i installed new and this is the kind of problem i'm having when installing the new compressor i used a can of i think its called 1st charge or something where it has everything for the first charge thats what it read on the can. i have a warranty on the compressor but he has been giving me a hard time about it and i just would like to figure it all out so i can get air thanks for the help
oh and his tech guy told me to replace the expansion valve? what do you think?
Not sure what you mean "filled it right where it should be" and this can of "1st Charge" sounds like bad news.
If you want to throw a new expansion valve in it, by all means. I doubt it's the problem, but since it sounds like there's so many improper service procedures here, what the heck. I can certainly understand why you might be having a hard time on the warranty.
