AFTER DRIVING ROUGHLY 38,000 MILES, MY MAZDA CX-7'S A/C STARTED TO HAVE PROBLEMS. IT STOPPED BLOWING COLD AIR AND STARTED TO MAKE A GRINDING SOUND. WHILE I WAS DRIVING TO A PLACE TO FIGURE OUT WHAT WAS WRONG WITH MY CAR, A BURNING SMELL BEGAN TO ARISE. IT WAS EVENTUALLY FOUND THAT THE COMPRESSOR NEEDED TO BE REPLACED AND THERE WERE METAL PARTS IN THE COMPRESSOR. THIS CAUSED HUGE DAMAGES TO THE CAR AND IT WAS ESTIMATED TO COST ROUGHLY $17,000 IN DAMAGES. IT HAS YET TO BE FIXED, BUT THE CAR HAS ONLY BEEN DRIVEN FOR 38,000 MILES AND HAD REGULAR MAINTENANCE INTERVALS. THERE WAS ALMOST NO INDICATION OF WHAT WAS HAPPENING BECAUSE I DID NOT TURN ON THE A/C OFTEN. *TR
