Question about 2001 Cadillac DeVille
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.

I just did this for my 1994 Camry. Does your camry use the R-134A modern refrigerant? Probably.
Go to an auto parts store and buy a can of R-134A with a pressure guage included. You'll need that guage so you don't overfill the system. I bought one that allows me to save the guage and buy cheaper refills int he future.
There are two AC valves. A small one, located in the left-rear of the engine compartment, behind the strut tower, just in front of where the passenger seat is located. It might have a cap on it marked "L". This is the "Low" port, and is the one you want. The larger "H" port is up near the battery, is bigger, and is the "high" port. You don't want to use that one, and besides, it won't fit the can anyway.
Locate that low valve in the left-rear of the compartment. Take the cap off (if one is still on there). Start the engine and get it up to running temp. Turn on your AC to maximum cool, fan at maximum. Follow the directions on the can. It's pretty simple.
You'll pull back on the bushing on the refill line, and then snap it onto the valve just like you'd find on an air hose. Snap it into place, and then start refilling. Make sure the can is upside down and that you rotate and shake the can to get the coolant out effectively.

i belive on this year car and make its located under the air filter box, remove the intake hose then the cover for the air filter, remove the filter then remove the lower part of the air box there you will see the filter dryer and the lines coming off the dryer and there will be two fittings to charge the ac system, the smaller fitting is the low side this is the side to charge through, make sure not to overcharge the system and add oil as needed, a good idea is to add dye to the system to help in finding the leak if system goes low again, theres a decal under the hood or on the dryer that tells you how much freon the system can hold. if you under or overcharge the system the air may be cold but future ac damage is for sure, good luck.
