Zeky Posted April 5, 2005 Share Posted April 5, 2005 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? Quote Link to comment Share on other sites More sharing options...
99obw Posted April 5, 2005 Share Posted April 5, 2005 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.

Zeky Posted April 6, 2005 Author Share Posted April 6, 2005 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?

99obw Posted April 6, 2005 Share Posted April 6, 2005 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. Quote Link to comment Share on other sites More sharing options...
Zeky Posted April 7, 2005 Author Share Posted April 7, 2005 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.

99obw Posted April 7, 2005 Share Posted April 7, 2005 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 Quote Link to comment Share on other sites More sharing options...

Zeky Posted April 8, 2005 Author Share Posted April 8, 2005 OK , so filled up and here we go its running strong Just need to know if i should put some oil in Quote Link to comment Share on other sites More sharing options...
99obw Posted April 8, 2005 Share Posted April 8, 2005 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. Quote Link to comment Share on other sites More sharing options...
Zeky Posted April 9, 2005 Author Share Posted April 9, 2005 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?
