If you are recharging the air conditioner - start at the A/C pump, and follow the lines up until you find a black round stub (this unscrews) and this is where you will re-fill (recharge) the A/C.
NOTE: It is recommended to have a professional (certified) mechanic recharge A/C systems, but is not necessary. (laws and regulations vary per state, city, county).
Please let me know if you need further assistance.
