Where do i recharge ac on a 2001 lincoln ls we only found i line

The one charging port is at the front of the engine compartment, look around the top right side of the radiator. The other one is at the back of the AC compressor, and can be found from underneath by removing the small splash shield in the front of the drivers side wheelwell.

You Can locate it beside the compresor underneath the car on the driver side

There has to be 2 lines running from compressor, or at least see if you can locate them up by firewall usually on passenger side at the "H" block. Bigger hose is low side.
