Don't listen to clown above, there is no schematics under the hood for the A/C system on any carline. Look for the A/C compressor. Look for 2 caps on the lines from the compressor. Most cars these days are both black, sometimes they use red/blue. But without looking at it for myself, find both caps. Trace the lines, sometimes it is on the firewall or close to the frame rail. Find the smaller of the 2, you want LOW SIDE. I want to point out that you should take this to someone who kows what they are doing, you can cause the can to explode if you don't know what you are doing. Also, if your A/C has lost over a certain amount, it may not take in any freon until you pull a complete vacuum on the entire system

Remember, if 1 can of freon cools this good, 2 cans doesn't mean it will cool even better. You need to know exactly how much freon is inside the system & the only way to determine that is to use a decent A/C machine & pull it all out. That way, if your A/c system still blows out hot air, you have eliminated the freon amount & go elsewhere with your diagnosis
