You should be able to get that at any parts store. They should at the very least be able to order it for you.

Have you taken a stethoscope to the compressor to see if you can hear the cylinder running? What worries me is that if it's just running all the time, then it may have disintegrated, or stuck. You could also try to add some compressor oil and hope that it frees it up.

 

I can tell youf rom experience that, the gauges arent always right as far as freeon goes, ive serviced many systems where the gauges read all the right pressures, but come to find out, that there was mostly air inside the lines, after we got the air out, we recharged it with the proper amount of freeon, and shabam, problem solved, back to ice cold A/C.

this may or may not be your case, but sure wouldnt hurt to check into it.

 

No, in our vehicles it is really easy to replace, the only problem is that you have to purge all your freon, then evacuate the system before doing a complete recharge.

The only way to check that would be to evacuate the system, but I would think air in the system would act up a little more and give you signs that there is something wrong. I believe there is a simpler way to check for air in the system, but can't recall right now.

 

ya, im pretty sure there is a way, but when we hook our hoses up, all we do is loosen the low side(blue) hose fitting at the gauge manifold, and if its not super ice cold(and i mean ice cold, pretty much turning into a vapor as soon as it hits the air), then you have air in there, and i would take it to someone who has a machine to evac. all the freeon, and pull a vacuum on the system, then fully recharge it with the proper amount.
