I have a 2010 mazda 6 and it took me awhile to find that port, anyways if we are sort of the same I found mine under the wiper fluid container
In this picture where is the low port?
SOURCE: where is the low pressure side port located for
as you are standing in front of car on left side behind air filter is a receiver alum canister with a cap on top this is the high pressure side just below the receiver and under the firewall you will see a cap this is the low pressure or fill valve
SOURCE: location of low side ac port
the low side charging port is near the AC Accumulator/Reciever dryer cannister in the larger of the 2 AC lines.
SOURCE: ac low side service port location
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
