Where do I charge the A/C?

Hello,

When you recharge the A/C system you will want to add the Freon to the low pressure line of the A/C house. The low pressure A/C service port for recharging the system on this Lincoln LS is located close the front driver side wheel well.
You will have to remove the inner fender liner to access it.
It will probably be easier to remove the wheel as well to access the service port.

Here are couple of helpful videos:

I have attached diagrams for your reference.

Please let me know of any questions.

Thank you.
