Air Con Need Some Help Please!

[Daboss]

Hey there. I just need some help from you guys with my ac please. I recentlybought a 95 r33 gtst skyline and my first question is if this type of skyline's ac runs off the 134a or the r12? Next the ac wasnt getting cold enuff for me, it was cooling but just not getting cold, so I decided to add more gas to it, i added the 134a and it immediately felt cooler now i have been running the ac for a day now and it blows nothing but hot air I did the diag nostic test and dont know what the results or what im even lookin for all the leds work i figured that out when i put it to 2 i get 20 when i put it to three i get 30 4 i get 41 and 5 nothing happens then six is a setting that you can adjust does ne1 know what this means. also when i tried to gas it first i put the hose on and let out most of the air that was already in it then i added two 12ounce cans of the 134a and it cooled for like a day very very cold i just went on a trip after playing with the diagnostic test and it is now blowing strictly hot air. Can ane1 offer ne solutions.

has it still got gas in the system? sounds like a leak to me.

I have been vexed by the way the auto function works but I think I have it worked out now. When I hit auto at 24c the air comes out the face vents but if i change to 27c it comes out the foot vents until 27c is achieved in car, then it changes to face/foot, and the fan slows to 1 unit, but if the car is cold, it wont up the fan from 1 unit until the motor water is hot enough to do the job. If I want cold air (24c or lower) on my feet I have to overide auto but it still keeps the temp range with the fan going fast/ slow etc.

yea there is gas in the system. i checked the diagnostics all is well checked the sensor on the left side of the steering wheel and cleaned it but still no cold air. i noticed the compressor comes on but then immediately cuts off what causes this and when it cuts on for that split second the little glass window that you check the gas level with is empty when it cuts out it fills up with a white fluid. can my compressor be shot? that would be a bummer cus i was using the ac all this week with no problems. decided to put more gas in it cause it wasnt cold enuff and now it doesnt cool at all. if i let the car sit for awhile and then cut it on with the ac it starts off like its about to cool but after about 30 seconds of that the compressor just keeps cuttin in and out.

also when regassed most of the previous gas was let out by mistake dont know if it was all, attached hose without refill bottle on next end resulting in the gas being let out, then two 12ounce cans (340 grams a piece) of the 134a were put back into the system could the problem be too much gas should i try letting some of it out. If so how do i go about doing this with car and ac on or just letting some of it out with the car off be good enuff?
