Whenever I turn on defrost I get this odd grinding sound coming from the front of the car. Now the sounds are not constant but is on and off. I would say like every 2 seconds I get a loud grinding sound. What is
odd is this doesnt happen when I just use the vents for heat it only happens when I turn it to mixed or defrost.
Any ideas would be greatly appreciated.
have the same problem?

Defrost setting turns on the A/c compressor, pulley bearing may be no good. Remove the serp belt and spin the pulley by hand, is it smooth with no binding?
