if you are pretty sure you dont have a leak this is what i did... the wires going to the high side cut off valve(the insulation came off and the wires crossed, so the valve would not cut off.. high pressure and the high pressure service valve blew.... i ordered another valve for $20 from the dealer and then went to auto zone and bought two cans of R-134A and a $19.00 service hose with a small meter on it to put some r-134 in it.. I have an old vacuum pump for the old R-12 system but it does not fit the new R134 hoses... so i just put some freon in the low pressure side and then let the R-134 blow out the high pressure service valve..... this got the air out... i then kept adding the freon in until the compressor finally came on and started pumping..... in no time one can was empty... i then attached the second can and it continued to charge up and the compressor stopped clicking off/on/off/on..........
just about finished the second can and it seemed like it had enough freon in it as the inside of the car was cold as can be expected.... that was about three months ago.. so far no problems... still works pretty good.....
when the old freon blew out the valve it did hot have any oil with it.. i checked around and did not find any on the lining of the hood or other engine parts so i did not have to worry about any oil loss.......
