Ok i went to Panama City a few weeks ago and got stuck in the sand. After getting towed out I noticed that sand would come out of my vents whenever the A/C was on. I thought I got it all out because after a minute or two most of the sand dies down, but everytime i use the A/C it will still come out. So my question is where do i look to get the sand completely out. Thanks in advance.

BTW it's a 99 3.0

 

The vents on near ur window. Check under your hood by near the front windshield. There is a grill there. That is where it might be coming in from. Maybe vacum or wash that area.
