As another here said ..... locate your evaporator inlet outlet lines usually coming out of the fire wall. then follow the line that runs to the compressor. that is your low side line and the service port should be on that line

The low pressure port is on the compressor on the bottom side. It should have a black cap on it.

It is on or near the reciever dryer or shiny looking thing at the right rear of the engine compartment. You need gauges to correctly add refigerant as you can overcharge it.

SOURCE: R134a recharger nozzle won't fit on low pressure service port.

The low pressure port on the 2003 grand am is actually behind the engine, near the firewall on the passenger side. Good luck getting your hose down there though, I ended up buying an extension hose.

93 Allante AC Compressor won't come on to recharge system


On most models you would need to jumper the low pressure switch while you are recharging the system. There should be a low pressure switch on the low side line and a high pressure switch on the high side or on the compressor.

I want to recharge the a/c of my 2004 Rainier, but do not know where the low pressure port is and the caps are not marked with L or H. Help! Thank you.


The good news is a that vehicle has R134A which means the quick release from your refill can will only fit the low pressure side which is normally a little higher than the High. Unlike the old R22 systems the Low and High pressure connections are slightly different in size.

Start with the simple and replace the fuel filter, what you have described is low fuel pressure due to restricted fuel flow from a dirty fuel filter.

93 Topaz A/C recharge


The port is either on the drier or just follow the largest a/c line.It is usually on or close to the drier.Sometimes the port has a blue cap on it.The low pressure side is the biggest line.Duracool is said to be more efficient than r-134a so it would be ok I would think.
