    You need to connect to the low side port. The low side of the a/c system will be located on the a/c pipe that goes from the a/c condenser to the a/c evaporator. Sometimes it will be on the a/c accumulator, but it can be anywhere between the accumulator and the evaporator.

    Ok... where is the A/C condenser and A/C Evaporator...

    ....or where is the Low side port located on a 1997 Nissan Pathfinder?

    look on the left side under the hood, as you are standing in front of the vehicle, the lines are running from the firewall, the cap is gray with a L on the top. you will have to buy a 134a hose and fitting to put in the 134a in to your a/c unit.

    you charge the unit from the low side, not the high side. they are marked on the plastic caps. you can buy a charge line and 134a in any auto parts store. if it is just low, you may need a half of a can to a can. this unit only holes 1 1/2 lbs. of 134a!!!
    if this does not make it blow cold you have other problems, do not keep putting in 134a! you will have more problems!!!!
