like a month ago i started my 91 prelude and a red light come on in the a/c button thats usally green. it did it a few more times figured it was nothing, now when i turn it on it makes a squealing noise i cant hear exactly where its coming from any ideads.

 

the red button is for you a/c compressor which is not working when the red light is on... it either needs a recharge or has a leak ,,,,
