2002 Ford F-150: working

This answer was rated:

I own a 2002 Ford F-150 5.4 litre Triton V8. The AC has quit working and only blows warm air. I'm trying to find the low pressure valve. The high pressure valve is readily accessible. Where is the low side hidden?

The low side pressure port is located on the Suction Accumulator/drier assembly. The drier is a cylinder canister that should be either black or silver in color.

Thanks, XXXXX XXXXX is the canister? I'm a novice who doesn't want to pay $800 for an AC repair just yet

It is located on the passenger side in the engine compartment. Below is a picture that should better help you.
