The low side port is up against the firewall, just behind the drive belt. the port is on the metal line between the evaporator and the dryer. a little rough to get to, but
can be accessed by the average DIY. not much room for the gauge and 134a can.
I'm trying to recharge the AC in my 1997 Chevy Malibu. What port do I connect the charging unit to?

Your service port will always be in the larger line of the two .. which is low pressure side. It might be in the dryer also which is low side.. your dryer is about 3 inches across and 8 inches long and also has your pressure switch for the AC compressor in it.. holler if you dont find it now... thanks Jerry

The ports on my 2005 silverado are on the same line,which is very confusing but, in between the two ports is the metering device (orifice) which changes the high pressure gas into a low pressure gas.The two ports are of a different size,with the low pressure being the smaller of the two. You can put your hand on the line, on each side of the metering device connection and the high side will be hot and the low side will be cold
SOURCE: where is the ac low side service port on a 2004
NEAR firewall engine compartment TWO aluminum tubes attatched to canister
follow to connector port ONLY one will connect to the AC kit hose
so you try it if it attatches its correct
you do have to unscrew plactic cap on the low side port connector
