Okay i replace my high end a/c line the one on the compressor to see if it was leaking because someone jb weld it i took it to see if it was leaking an no leaks so i bring it home to put freon in it, at this point its 75 degrees out side and 3 months later its 90+ outside a/c not cold no more a/c stays on but when i ramp the engine the clutch turns off i checked the freon it stays in the green when idle.when driving its cool but not cold.
Did you vacuum the a/c before refilling?If the a/c is cool not cold try giving it a little shot of 134a to see if it drops a little colder. You should see a dash vent temp of 45 degrees with med fan speed,when there is air flow through the condenser at the front.Use a fan in front of the rad when filling a/c.

the bubbles are just air in the system, it will eventualy go away. are you sure the leak is from the pump or is it just comming out the cap because of the air. also did you chk. the pressure line? that maybe where your leak is. unless you got a crack in the resavor, its most likely the pressure line. there is a pressure line and a return line.

That's the power steering pressure switch and it is very easy to replace. I don't know how much the part is, but it cant be very much. It's a very simple switch. I'd just replace it.
SOURCE: not cooling
your low for 134A should not exeeed 45 Psi and highs for 134A shouldent get above 300. When your replacing stuff are you cleaning out the residue from your evap and condensor prior to reinstalling Freon?allso adding oil. and vacumeing your system prior to charging helps to get all the moisture out. In high humidity its crutial for optimal cooling and when system is open to the humidity for some time it gets loaded with water and vacuming can sometimes take as long as 10 hours
SOURCE: Changed Compressor not blowing cold enough
If you tried using a refrigeration "sealing" product before changing out the compressor, you most likely do need to replace the expansion valve.
The valve "flutters" open/close/open/close/etc/etc when in operation. The purpose is to allow the compessor to build up enough pressure to change the freon to a gaseous state. Once you put in the sealer, the valve becomes plugged with the product and cannot seat completely. After this happens, you never get a full phase change because the pressure cannot build up enough. You will experience reduced cooling. Change the Exp. valve and you'll be set. In the future, it is not advisable to ever use the sealer products as this can cause damage to other system parts, and especially the recovery units at the shop.

Check vacuum lines going to evap canister for cracks or splits, causes to much raw air intake.
