SOURCE: low-pressure port I need identification

Basic AC system consists of Compressor pump (on engine), Condenser (front grill with radiator) and Evaporator (Firewall). Pump has two ports output (high pressure) and return (low pressure). Follow lines from pump. High side is usually between pump and condenser. Follow lines and find second port this will be low side (refill) port. Paint or replace port caps (red high, blue low). Also, refrigerant in system determines port size (R12 or R34).

THE LOW PRESSURE LINE IS ALMOST ALWAYS LOCATED ON THE WIDER PIPE OF THE 2 AND SOMETIMES THEY HIDE IT UNDER THE AIR CLEANER ASSEMBLY.

Where is the port to charge my air conditioner
There are 2 ports, a high pressure and low pressure port. Both are in the engine compartment. I would suggest you get someone who knows air conditioners to do the work. This can be dangerous since Freon is extremely cold and can cause burns (freezer burns). Also you can damage your air conditioning system, and then it will cost big bucks to repair.

The controls of air condition for my 2005 chevy malibu dont work
If the AC fails to provide cold when it is turned on have the AC system checked for a low charge of refrigerant due to a leak in the system. If it islow it is likely the AC compressor front shaft seal is leaking.

Ac charge for 2001 chevy malibu I need to find the right pressure port on the fire wall a picture would help or really detailed instructions i found one pressure port but it was to large for the hose i...
If you are gonna charge Freon, you are looking for the LOW SIDE pressure valve. Most of the time its located on the low pressure hose or the evaporator itself.Look for a HUGE black cap most of the time its that color your freon can if it came with a hose attached will only fit the low side connection.

Need to recharge 2003 chevy malibu air conditioner. where do i find the intake to recharge it.
under the hood there is two a/c valves, one says H for high side and one says L for low side... hook up to the low side and turn the a/c on max with the car running and then charge. you really need a pressure gauge to know how much to put in. too much freon will make it blow hot also, you need the right amount of pressures, just go slow filling it up and keep checking the a.c temp out of the vents.

Where is the air conditoner low pressure service port
No offense, but if you can't find the low side port, then you have no business trying to charge or otherwise fix an A/C system.
It's dangerous.  Hook up to the wrong port and the freon can goes off like a grenade in your hand, freezing whatever it fails to blow away.

AC is not working
Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.

Air conditioning not cool
The charging port is in the larger of the 2 AC lines from the AC compressor on the engine, it will be near to or in the round cannister (called an Accumulator) that larger AC line goes near the firewall at the back of the engine bay.
