AC wasn't warm but not as cold as usual, I've had this car 3 years and no AC work done, not sure if there was any done prior to my ownership....had dad put some refrigerant in and it started getting warmer instead of cooler, can was empty so we left it alone. Next day omw to work nothing would blow out, me knowing not much about AC systems thought he overfilled it so I let all refrigerant out. Ec light came on, I started researching and realized the blower wasn't on, I took apart the dash an cleaned up tge blower motor and it started back working, tried adding refrigerant but gauge showed too much pressure with less than a can put in, I let all of it out of system so it should be able to take in minimum 2 cans, anyhow did more research and learned the compressor needed to turn on for freon to circulate, after 2 days of trying different things, including vacuuming the system and recharging, I learned how to reset it by erasing codes in climate control dash, it worked, compressor came on but is still showing really high pressure while putting in refrigerant, warm air still blowing out too. Well kept messing with it and decided to check passenger vent and it was blowing cool, drivers side still warm, added more freon, got a can, well almost can to go in, now I have about 23ounces in there, maybe 24, drive to the attire and while car is moving the driver side blew cooler, not a cool as passenger, but cooler, when I stop it goes back warm on driver side. I went in the store and when I started car EC was back on...ughhhh...I reset again, compressor clicked backed on, but is of again, it comes on every time I reset it but I have to reset after I turn car of more than 5 minutes now. Btw, while vacuuming it pulled to -31 & held that number fit 20 mins after I turned off vacuum so i'm assuming there is not a leak in the system...can I get some clues of other things to check, i'm kind of broke so am trying to do this on my own but am getting totally frustrated now. Thanks in advance. S/N... I vacuumed again after getting the compressor to come on as well.
