Thanks for the info. I checked today and there was power on both sides of the fuse in the block under the hood. It is probably like you said the switch because when you turn the fan switch on when in the defrost mode, there is no power going to the a/c nor the recirculating switch. Going to a dealer and will let you know what it was.

Update: checked at a friend's shop today and found that it was indeed the switch that was gone.
