welcome Matt

why are you asking about the drier,a/c not working? have you run the onboard diagnostics?

Reverse is also true

follow the line from the evaparator to the compressor that is the low side line.It has the small fitting so you can't goof it up adding r134a the tube will only fit on the low side port,sort of runs along from the right side of the block back to the firewall,plainly visible on the aluminum tube.

get back here if you haven't run the tests,and if the a/c is not working,lots to check before you toss in more a/c gas
