Excursion A/C not cold

My '03 Excursion v10 is not as cold as it should be.

Idling on a hot day Im only getting 65F out of the vents. The X is black, and Im in Houston.. so please help a brutha out

-Compressor clutch engages correctly and compressor continues to run as long as needed
-R134 level/pressure is good
-Condenser cleaned/degreased
-Fan Checked and working well/ giving good airflow

Look at the gray vacuum line that runs from your right side just over valve cover to rear of ac fan on outside fire wall.

Mine had popped off... I put back in and all was good.

Also, check your compressor clutch gap. If it's too wide, the compressor is not engaging.

Yessir, done.

The gap is good and the compressor engages and stays engaged when necessary
