    Okay, I thought that I had someone that knew what they were doing recharge the car, and they hooked it up to the one under the air filter, if that is the high side(possibly) could that hurt the system?

    the high side hose is the wrong hose to charge the car, all AC systems are charges on the low side hose. shouldn't really even tell u this but don't want you to hurt yourself.

If you have a refill kit, the hose will only connect to the low side hose. Most likely, the hose under the filter is the high side hose. Hope this answers your question. Best of luck.

p.s. When recharging AC, have engine running and AC on HIGH

    Absolutely don't ever charge the AC on the HIGH side. This is dangerous and should be left to the professionals. The refill kits that auto parts stores sell have a hose to deliver the refrigerant. The hose is designed to only hook up to the low side.

Where is the low side service port for the air conditioning system?

Look close to the fire-wall in the area under the driver's-side windshield wiper. If you're adding refrigerant with the system from an auto-parts store, the fitting on the hose will not fit the high-side port, only the low-side port. Also, there should be a black plastic cap on the low-side port.

Air conditioning

When an vehicle's air conditioning system has not been used for several months, the seals within the system start getting dry. I've never worked on a Peugeot 206 or any other peugeot before, that's why I had no idea where the low pressure ac port was. The high pressure ac port is the easiest to locate, because it is in the engine compartment, facing the car from the front, on left side of the radiator. The low pressure ac port is in the engine compartment, facing the car from the front, to the back in the center, under the windshield. The low pressure ac port and the high pressure ac port both have black dust caps. The low pressure ac port is the smaller of the two.

Where is low port to recharge ac?

Near the firewall you have both air cond pipes coming out. There is a black cap on the larger of the two alum pipes. It is under the air filter housing and should be able to see it without removing the air filter housing. That is the low pressure side.
The high pressure should run along the chassis rail and near the radiator there is another black cap on a smaller alum pipe.
Remember always yes always vacumm the air cond system for at least 3 hours to dry out the air cond system correctly. If you don't if will only work for a short time before playing up again.
Some shops don't do this and wonder why a car keeps coming back for more gas. Good for them bad for customer.

Where is the low pressure port for the air conditioning on my 95 cirrus lxi?

Just look around for it - it's obviously going to be on one of the A/C lines - possible under the engine cover. They can be tricky to locate but just keep an eye open - they usually have a black cap on them. There's 2 ports, high and low - the smaller one is the low side.

Where is the cap to recharge the a/c in a 1997 Chevy Malibu?

It is either under the filter box,where the air cleaner goes,or next to the firewall next to the passengers side fender,look at the ac lines coming from the ac compressor,and follow them,look at the large ac line coming from the ac compressor,to the firewall,it will be on that line,and your single charge hose,will only fit the low side service port,so you can not hook up to the wrong one,if this was at all helpful,please rate,thank you.

I have a 2002 Impala 3.8L
There is one port between the air filter box and strut tower (driver's side). I'm pretty sure that's the low pressure port.
The high port is against the firewall behind the engine, about in the middle.
The ports are covered by black caps.
