Hello,

Here is a guide to help you see what you are in for when recharging the system

The low side service port will be on the return line from the firewall to the compressor.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Thank you I found the fitting down low. The high side fitting is easy to get to on top.
