add couple cans of r134a w/ oil and sealer for 10 bucks a piece and your ac will work (not the best it ever did but enough) for around a hundred bucks. if you look around you can find it cheaper i bought that gauge set for $17 bucks and the pump for $9.
step 2 charge a couple people $50 each to fix their ac and you got yours for free.
