hey guys i really need some help with recharging my a/c. never done it before on any car. The Haynes manual isn´t really a help and the back of the r-134a package isn´t either. I need to find the low pressure line and recharge at that point but i don´t know where the valve is. The one that i found seems to be the high pressure line (it sends the pressure gauge well into the red overcharged area). I´m going away tomorrow and would like to have a/c so any help would really be appreciated. Thanks!!!
