SOURCE: AC has stopped blowing cold air. Compressor is working. Where is the recharge valve located?

There are two A/C refrigerant lines. The small line is your high pressure line and the larger line is your low pressure line.
Start at the fire wall and follow the "large " low pressure line to the compressor. The low pressure charge port will be some where on that line.
DO NOT try to recharge on the high pressure side ( small line )
Good luck, let me know.

Where is the low port located in the engine to recharge the ac for a 2008 Chevy Malibu LTZ 3.6 v6


The low pressure side to the ac will be the Schrader valve that is the smallest size. If you are recharging it yourself try to fit you valve on both valve and you will see what I am talking about.

How to recharge ac


There are many ways to recharge an ac system but to do it correctly is a bit more in-depth. You can read the ac tag under the hood of your vehicle and purchase a can of coolant then hook it up to the low pressure side as shown on the can. Start the engine and follow their instructions. If you have a leak you should add UV dye to the system to locate the leak then repair as needed. To recharge system I recommend purging the system to a proper catchment contaner, recycle the refrigerant as required. Put an ac manifold on the high and low ports of the ac system (they are sized to only fit in the proper location) then attach a moisture removing vacuum pump create a vacuum in the system of 20lbs at sea level or more. Close the high and low pressure valves and disconnect the vacuum pump connect the refrigerant to the vacuum line, start the vehicle, turn on the ac (fan on low) add the amount of refrigerant that your vehicle tag requires.

Warning light says Low Refrigerent-AC/Off. I tried to recharge the system but the Compressor won't engage, How do I get the Compressor to come on so as I can recharge the system. Is it a pressure swithch...


in order to recharge the ac you first must clear the trouble code for the ac off warning. when you get this warning the computer shuts down the compressor to keep it from running without the lubricant that is in the freon. clear the trouble code and the compressor will run and you can recharge the ac.

Air conditioner blower stopped working on 2004


If the blower works but its just not blowing cold air, its possible to recharge the AC system yourself. Most auto parts stores carry AC recharge kits. Instructions to recharge the AC are belowl

RECHARGING AC SYSTEM

1.Turn the truck on and turn AC on HIGH
2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
4.Insert the other end of the refill hose to the low side valve
5.Puncture the R-134A can with the screw on the refill hose
6.You should feel the system suction the refrigerant out of the can
7.Check for frost on the AC lines and the air blowing inside the truck
8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective


Best of luck and enjoy your vacation.

Hopefully this answers your question and you're able to get your AC working again. Best of luck.

I need to retrofit and recharge my 1988 Dodge Ram Ac.


First, the old R-12 must be completely evacuated fromt the system. R-12 and R-134A do not mix and won't function together. Once you are sure there's no R-12 left in the system, you need to install an R-134A fill valve on the low side AC line. This is where your refill hose will connect to add R-134A. Once the valve is in place you're ready to fill the system. The compressor requires a minimum of 20psi to engage and should not be filled to more than 45psi.

1.Turn the truck on and turn AC on HIGH
2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)

6.You should feel the system suction the refrigerant out of the can

Low Pressure Valve 97 Grand Am


The low pressure valve is down by the AC Compressor. It is part of the aluminum manifold that connects directly to the AC compressor. It is accessible from above, but easier to reach from under the car.

By the way, is there any particular reason why you want to recharge your AC system? If it isn't working, adding refrigerant will not necessarily fix the problem. If the refrigerant has all leaked out, you probably need to evacuate the system first.

Ac highside charge line location


the high side should have a black cap with a letter H on it.... if you dont see it then look for 2 valves that have caps on them, the larger of the valve is the high side, the smaller is the low side, the low side is the only one you want to use if you are refilling the system you do not want to mess with the highside... the low side pressure makes it so you can recharge the system, the highside will not work to refill a system if you are using the store bought recharging systems... and the valve on the recharger will only fit low side... hope this helps you... the highside should be on the pass. side towards the rear o the engine...

Locating low pressure valve on 96 explorer for ac recharge


The largest diameter line is the suction which is low. The small one that runs to a coil by radiator is high pressure. If there is no cooling then you may have air in the system which means a leak must be fixed first. Are you sure the compressor is engaging? You should hear it click and the engine bog down a little.
