[img]smileys/smiley19.gif[/img]has anyone encountered their a/c making a vibrating noise while it is running? mine does. after i turn the a/c off by pressing the button, it stops. i havent been able to figure out what it is. if i am driving it doesnt make noise, it just does it when i am coming to a stop. can anyone help me with that problem it is very annoying. thanks

what vehicle and how old? do you use your AC all the time?

[img]smileys/smiley4.gif[/img]heh!! sorry that info would help right? well its for a '92 rodeo v-6 4x4. thank to anyone who helps.

ok..try this....leave the AC button off, and turn the defroster on to full blast...and see if the noise happens...if so, it is the compressor.
