How can i recharge the air conditioner? Where is the hose located?
Ok if you want to do a home repair in hopes of saving yourself a lot of money and with hopes your system is not in major trouble, here goes:
First step buy 3 types of 1 lb. cans of refrigerant R134a at a parts store, 1 can of leak detector freon combination, and if possible 1 can freon/air conditioning oil combination freon along with 1 can of straight r134a freon.
The store will sell you a charge hose with a cheap type of charge gauge attachment and fittings to attach to your system for the re-charge.
Providing your system is low on freon,First, with the vehicle running and the a/c on full cold, high fan, install the 1 lb. can of freon/oil combo first only charging through the low pressure side of the system never through the thin line high pressure side as the pressure from the high side can enter the cgharging freon can and explode it like a bomb,(this low side line is the larger hose and the low side charging hose fitting the parts store sells you will only screw onto the low side charge valve which is normally marked "low" on the top of the plastic dust cap that is factory installed(hand screwed) on the low side valve fitting.
Secondly after the oil/combo can is emptied into the low side and you of course are wearing mechanics hand protection gloves and eye protection googles, then and only then will you install the leak dector 1 lb. freon can combo.
Third you will install the last 1 lb can of r134a freon, however your vehicle will not allow the whole last pound of freon into its system by means of a pressure relief blow valve that will automatically blow off any excess pressure once the system over fills, the system typically holds approximately 2.75 lbs. of freon.
If you have successfully installed the above freon into the system it should be up and running providing the system is in fairly good working order, by that I mean it may have a very slow leak that allowed the freon tio originally escape in the first place causing you to refill it, and if it does have a leak the leak detector die that you installed into the system should leak out from wherever it may be escaping from, indicating the place of needed repair by means of a red or blue, or whatever other designated coloration the die gives out from the leaking area.
Please note: Not all home charging techniques typically work as there are many mechanical failure factors in an a/c system that may require a certified a/c technician to determine exactly why your system is not working should the home remedy fail.
I hope this helps you and remember to always work safe with eye and hand protection especially around freon gases which become extremely cold and can cause frost bite when contacting with the bare skin.
