April 5, 200520 yr Hi, can anyone tell me how to find out if the A/C compresor is OK.Well all relays seems workin and clutch on compressor also.A/C system is not exactly full but not empty at all.All A/C hoses are hot.And two weeks ago everthing was fine.... So? Any ideas?
April 5, 200520 yr So the clutch is engaging on it's own? What is the low-side pressure with the system running? If you have dual gauges the high-side pressure would be helpful as well. I have found that the R134a systems start to perform poorly with only a relatively small percentage of the refrigerant missing. Is the A/C fan running? A poorly cooled condenser will cause poor performance as well. I assume the evaporator fan is running? I'm no expert but I do have a decent book and I will help if I can.
April 6, 200520 yr Author 1.clutch is engaging when the A/C switch is pressed 2.System is R12 3.Evaporator fan is running 4.Pressure on the thinner hose is little bit under "FILLED" mark.I got only Gauge A/C filling set and it shows only LOW-FILLED-OVER FILLED Thanks for your help So the clutch is engaging on it's own?

April 6, 200520 yr Can you get R12? If so I would top it off. If not you may consider converting the system. Is the condenser fan running? I can look up the symptoms in my book when I get a chance.
April 7, 200520 yr Author Consider fan is running ,but i think it may be already converted... BUT HOW TO KNOW http://www.ultimatesubaru.org/forum/showthread.php?t=33889 I appreciate your help Can you get R12? If so I would top it off. If not you may consider converting the system.

April 7, 200520 yr The R12 has a screw-on fitting similar to a Schrader valve or tire valve stem. The R134a has a snap-op fitting similar to an air hose. If it has been converted a snap-on fitting has been screwed on to the screw-on fitting's threads. http://www.id-usa.com/product.asp?CID=38&PID=143
April 7, 200520 yr Author This is what i have ,so it has been converted but still doesnt work :-\ Later today or tommorow i will try to fill it to top and let you know... THX
April 8, 200520 yr Author OK , so filled up and here we go its running strong Just need to know if i should put some oil in
April 8, 200520 yr It's really hard to know for sure. It's possible (probable?) that some oil leaked out as the refrigerant was leaking. I would probably put one of the small cans of oil in, 2-1/2" oz in the US IIRC. Be very careful not to get too much oil in it though. The system won't work very well with too much oil. Ask me how I know.
April 9, 200520 yr Author I would probably put one of the small cans of oil in, 2-1/2" oz Yeah ,thats what i am thinking about.And by the way i am now living in US :cool: And just share your pain and tell us what u did with your A/C :banana: :banana: :banana: love this smile ...banile?
