im pretty sure my a/c is completely gone. its been leaking for a while, and now its not even cold and the compressor comes on like every 5 seconds. but tonight when i started up after work, i got this really weird "winding" noise from under the hood. so im pretty sure thats gonna need replacing soon with summer coming up

 

You lost too much oil out of the compressor along with the 134A leaking out too.
