    Default Orifice Tube Location 1999 Yukon

    Can anyone tell me where the orifice tube is located on a front air only 1999 Yukon?
    Thanks

    I think it is in a connection on an A/C tube about half way between the A/C condenser (front of vehicle) and firewall of the truck.

    If the A/C is running, it should be cool or cold in the tubing past this point.
