Where is the low side AC port on a 2006 Jeep Commander?

The low side AC port on a 2006 Jeep Commander is located on the driver's side of the engine bay. It can be found on the larger diameter aluminum line that runs from the evaporator to the compressor. Look for a fitting that is typically capped and may be marked with an "L" for low side. Make sure to check under the hood when the engine is cool for easier access.
