I would like to confirm if the signaled in the picture is low pressure air condition valve ,

thanks in advance..

Is the one surrounded with a red shadow.

 

No, that is the high pressure location. The low pressure valve is located on the accumulator/drier.

 

Seems to be my confirmation was totally wrong.., so in that case will be the one sorrounded green isn't it.

thanks a lot

Please see picture.

 

Correct, that is the low pressure port and is the port used for re-charging with r134a refrigerant.

 

Thank you 1998MSO.., I do a lot of things in my car but air conditioner is something I never deal with., with your support and some reading in internet about how air conditioner works., let me tell you if the problem is running low of gas ., it is not necessarily a leak and reload the gas is a very easy task that you don't need to pay 60 or 70 bucks , just get the recharger unit from advance or autozone and with 25 your problem is fixed.., my air condition is blowing now cold and nice.

 

Glad your A/C is working again. Hopefully you have only a very small leak and you'll be able to use for awhile again before recharging.

 

You must have a leak as that R134a went somewhere. Liek 1998MSO says, hope you get the rest of the summer usuage before it stops working again.
