Default A/C Leak?

2 weeks ago I charged my A/C because it wasn't blowing cold anymore. Today when I decided to use it, it wasn't blowing super cold; my drive home from work is ~5 minutes and I had it going at full blast and it didn't seem to cool as much as I hoped. When I have the A/C I notice quick a bit of water dripping from the metal heat guard above the passenger cat and didn't know what to make of it. Any ideas? I don't see any leaks from any hoses or the compressor. However, when I turn the car off with the A/C running I can hear, what sounds like, pressure being released and it stops after 5 seconds. Another thing, after I recharged the A/C the accumulator was pretty chilly to touch; now it barley gets cold.

Any ideas?

The water dripping is normal as is the accumulator being cold, and the vacum/pressure noide you hear.. Your best bet is to have some R134a dye shot the system & checked for leaks.

The accumulator isn't cold though; there is zero condensation on it. Plus, it sits no where near the heat shield.

Go and get some refill with the dye in it. Recharge the system and look for leaks that way.

Put some R-134a with dye they sell a uv lite that you can use after a few hours after you put the dye in. Shine the light all around the a/c compressor, dryer, hoses every where that the r-134a runs threw. If you see dye anywhere around the places listed theres your leak. It would be best if you find someone with a r-134a machine that will pull the freon, fix the leak if you have one, pull a vacuum, then recharge the system.
