Trying to recharge my AC. Everything seems to point to the only Port I can find is at the passenger front of the engine compartment by the headlight. But it’s on the smaller diameter of the two hoses. The larger metal hose has no port at all…at least that I can tell. Many videos shows that the port I’m looking at up by the passenger front headlight is the correct port to recharge the AC but again I’m not sure. It doesn’t have an L on the So can someone confirm where the low pressure port is for recharging your air conditioner on a 97 1500. Thank you

Follow the lines back to the firewall.
With 134a automotive fittings are two different sizes, the low side is larger

Thanks Crash. It turns out that mine IS that port ultra visible right at the front of the engine bay, passenger side. Frankly, found no other port. I was able to resurrect the AC on my 'new truck' that sat for 6 years. When the compressor first kicked in, I was excited - that it wasn't seized (liked the alternator) - and then, as the can of refridgerant emptied, that cold air started blowing inside the cab.

Yeah baby!
