Any A/C experts Please Read! OK here we go.... I drilled a hile in my A/C condensor 2 years ago while installing a SLP CAI (lol) so I bought a new one and Installed it... waited till spring to fill it up... Filled the whole thing up... didn't work i pulled the orfice tube and it turns out that i exploded the compressor... no biggie... Bought a new Compressor and a new orfice tube, a new accumulater and i had the new condensor... so I had it professionally filled... it wasn't the coldest A/C on the block but it worked... so then my EGR line melted a hole in the line that goes from the firewall to the condensor... man what luck... so i left it off for a few weeks while i was waiting for the new one to arrive... so... I put a new line in and while doing so I put a crack in the tube that goes from the firewall to the inside of the car... so I put it away for the winter.... today I used some steel puddy and wrapped the line where the crack was... I preety much patched it all up presto no more leaks! well I went to fill the system.... I filled it up and the compressor kicked in... it was a beautiful thing... then i put my hand by the vent and it was hot.... so i bled the air outa the system from the condensor line.. filled it back up and it was the same... well it is sitting there full as can be but the air is luke warm at best... not leaking compressor is kicking in.. new condensor, accumulater and orfice... whats wrong!

There is a number of things it could be. U need to get some gauges on the high and low side. More than likely you have something clogging the system for it being exposed that long. I would advise taking to a reputable a/c shop and have them flush the system completly and start over. Too much oil in the system causes cooling problems as well. Or the thermostatic switch inside the car may have went out as well. Vaccum lines may not be opening the damper door right etc.

BTW if u put puddy on it.. well u just cant do that i dunno what line you fked up but you got you got a massive amount of psi on all points of the AC system and any ***** job is just gonna fail or last only a week or 2
PM if u have any more problems just got my cert for AC systems last week
If the old compressor detonated bad enough it stopped up the condensor and not amount of flushing will get it clean. You can't half *** fix stuff like you are doing with airconditioning and expect it to work. The system to needs to be fully flushed, replace the dryer,replace the condensor and the liquid line to the evaporator install new orifice tube and drain the compressor of oil and fill the system with eight ounces of fresh oil. Then evacuate for 45 minutes to an hour and charge with fresh refrigerant. If you replaced the compressor with a parts house pos and not a genuine gm then expect to be doing all of the above over again very soon. Good luck and dont cut corners if you do the result will be what you are complaining about.
i'm gonna have it leak tested at a shop... I used the steel putty that hardens like steel.... and i used it on the line that connects the firewall to the condensor... and I had the system up to full pressure and the line itself was pressurized and it didn't leak..

OH here is what I wanna do.... I wanna check for leaks before I bring it in for the Flush /Evac/ refill..... SO what do I do buy a small can of R134 and put it in the system and see if it holds it over night? ..... I checked my orfice tube today to see if there was any metal in the system and there was a green liquid that just trinkled out of every tube... I'm assuming this is oil and there is too much in my system? So knowing this do I need a flush? or can i just have it evaced and refilled?

It sounds like the refrigerant that was added also had dye in it you can buy cans with it. It will say uv leak detectant somewhere. Since you changed all of that you are on the right track.. IS the orifice tube installed in the correct direction. I have seem people force them in, in reverse a couple of times. When it is running and not cooling give me some pressures on the suction and discharge side and we can go from there. If the suction line is cold and the pressures are right you may have a problem with the blend door in the air box that mixes air from the heater. I have ran into that a couple of times.
