Diagnosing A/C leak in 98 Cavalier

Hi everyone! It's nice being here and big "Thanks!" To any advice. I have really good common sense and I do know that a/c problems are best left to pro's. The problem is I am disabled and I have MS. The hot summer makes me sick and I cannot afford a mechanic so I need to try this myself. The good news is the a/c DOES work and blow cold. The bad news is it leaks out in about 3 days. Is there 1 particular place I should look for leaks? Are there rebuild kits to replace vulnerable gaskets or seals? I assume I am going to have to rent a high powered black light and use dye in the system.

Thanks for any good direction anyone can get me going in. The unit really doesn't look bad. I'm just curious how many place's it can leak the coolent gas from

If it's leaking out that fast you should be able to see oil where it is leaking. Check everywhere there is a fitting in the system, especially the backside of the compressor.

...and another thing. If you don't see any oil you may need to do a bubble test. Mix up a bubble solution in a spray bottle and spray down all the connections and look for bubbles to form. Of course to do this you will have to put some freon in.

Check Amazon.com for a 134A leak detector for $11 plus shipping, also
Big Lots has 134a for $8 a can.

Check both the low/high pressure side schrader valves.
