well im not 100 percent sure if its the a/c or not... Right when i turn on the car and the a/c is on the car makes a real quick squeaky noise then when it idles the squeaky noise comes back .... then i turned off the a/c and then started the car again and there was no noise... i have no idea what it is ... Does anybody know what it might be

 

how about if you leave it running with a/c on, then turn a/c off... does it go away then?


and does your a/c blow cold?

 

its not that cold... yes the noise goes away then

 

Get your belts checked, and you a/c pulley

 

my belts are fine... could it be my a/c compressor

 

It could be, alot of things squeek.

 

When was the last time they were replaced? Is there any wear on them, they could be lined up a little off.

 

all of that stuff is pretty much stock except for the belt ... what would i have to change?

 

i know in my first newer body silverado, i took it off-road in a bunch of mud and water, and for the next year or so, the AC pulley squeaked when the ac was off, and when the ac was on it squeaked even worse

 

hmmmmmmmmm
