Which port do I use to recharge my A/C/? I see two ports with black caps and one with a green cap. I know it needs to be filled on the low pressure side, but I dont know which one that is.
I believe the recharge kit will only work on one of those ports. The ports should be different sizes. Whichever one it fits on should be the low pressure side. I don't know if that's the "green" side. I haven't had to mess with any of my cars AC systems in a long time. Pearl02.
