How do I recharge the AC on a 2002 Infiniti G-20? on 2002 Infiniti G20

The AC stopped working and my wife was told by a shop that we had to replace everything ($2500) when I was out of town. She told him she didn't want to do that and then he backed it down to a little over $1000. I want to recharge it and see if I can find a leak and work my way from there.

first of all, find another shop for a second opinion. it sounds fishy from everything down to less than half.

then figure the route you want to go. recharging will do nothing but leak out without repairing the needed stuff.

I recommend you use a shop as ac work is dangerous if you have no expierence.
