i replaced an a/c hose today that had a hole in it...the one that goes from the compressor that bolts on to the front of the condensor...
#3 on the diagram


so i then filled it up with 3 oz of pag46 oil and 23ish ounces of freeon...
a/c compressor comes on, air comes out, but not cold
even let it run for 25 mins at full blast

so i then drained it completely from the top service hose and filled it up with 2 ounces of pag oil and 12 ounces of freeon=same problem

please tell me whats wrong! thank you

did u use gauges to tell you when you have reached a full charge??...now u said u used Freeon?...i hope you are talking about 134a..cause freeon is for older vehicles...everything has switched to 134a now....

lmike6453

yea i used 134a and used a gauge..even overfilled it to see..how many psi is it supposed to be at??

lmike6453

bump..need to get this working...any way to make sure the condenser is working? the condenser fan comes on

lmike6453

ok so i hear that i may have to have all the air suctioned out of the system? all i did was replace a hose...anyone ever hear of this and how to go about it???

yeah thats another problem that is affecting it...sorry i neglected to add it last night...yeah you need a vaccum pump to but a heavy vaccum on the line which that will also take all the condensation/water out...cause under extreme vaccum water boils ....then once u have the vaccume on it, try then to replace 134a

yes i agree with the bold statement

Traped air and water in the system will both reduce the a/c compressors efficiency. Water is non-compressible and air has no cooling affect like R134. Take it to a liscenced shop and have them pull a vacuum and perform a leak test. Best $50 you can spend. Then have them recharge it for you. Low side PSI should be around 30-40 psi depending on ambient temperature.
