I am trying to add Freon to my truck because the A/C just blows out hot/warm air. Having trouble locating the correct Valve. I found the "HI" Valve but not sure where the "Low" valve is. Any help would be greatly appreciated. thank you.

Hello,

The low side service port is on the low side line near the accumulator. Here is a video that shows how to find the port on any car with diagrams below to show you your truck.
