My A/C has been dead since I got the car - it's been winter for most of the time, but now that's it's effing hot outside again, I was reminded that I really ought to look into that.
I supposedly have UV dye, but I don't really need to use it to realize that there's a huge green stain that is clearly a leak originating from the connection between one of the A/C lines and the condenser (the one on top)
Can I just wrench off this line to take a look at the o-ring or whatever? Will I let the refrigerant leak, or is it all somewhere else with the car off? Or does it not matter at all because all the refrigerant is gone anyway?
