    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 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 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.

NEED TO FIND LOWER PORT FOR RECHARGING AC


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.

These ports are usually covered with blue plastic cap. Remember to always service on suction/low pressure line only, the low press. line is the large line coming off the compressor.

My recharging kit for air conditioner doesn't seem to fit recharge valve on 2004 dodge durango. How can I be sure i am looking at the low prerssure valve?


Newer vehicle come with R134 vs R12. Since the two are not compatible, R134 has larger fittings. AC system has two ports, High and Low. Low is return to AC Compressor and high is output. High port is first following line from compressor to condenser (condenser is at front of vehicle like a second radiator). Keep following line till you find high port (paint cap red). Second port is low (paint cap blue).

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.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi

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