NHTSA Complaint #10213710 — 2007 GMC YUKON

ON THE DASHBOARD, THERE IS A BUTTON WITH A STICK FIGURE IN A SITTING POSITION AND AN ARROW AT THE FEET OF THE STICK FIGURE TO INDICATE AIR TO BE DISCHARGED AT THE FLOOR BY THE FAN. WHEN I PUSH THAT BUTTON FOR HEATING, UNFORTUNATELY, 80-90% OF THE AIR IS BEING DISCHARGED AT THE TOP OF THE DASHBOARD THROUGH A SMALL VENT ON THE FAR RIGHT AND LEFT OF THE WINDSHIELD, WHICH ARE DESIGNED TO BLOW ON THE PASSENGER AND DRIVER SIDE WINDOWS TO DEFROST THEM. THERE IS ADDITIONAL LEAKAGE OF A SMALL VOLUME OF AIR AT THE DEFROST VENT FOR THE WINDSHIELD AND, WHATEVER'S LEFT, BLOWS ON THE FLOOR. THE NET RESULT IS THE VEHICLE IS PUMPING MOST OF THE HOT AIR TO THE CEILING (BECAUSE THE SMALL DASHBOARD VENTS POINT UP) WHERE HOT AIR NATURALLY WANTS TO BE AND IT IS VERY DIFFICULT TO GET HOT AIR ON THE FLOOR WHERE, ACCORDING TO THE OWNER'S MANUAL, THE MAJORITY OF THE AIR SHOULD BE DIRECTED. THE COMPARTMENT, THEREFORE, TAKES FOREVER TO WARM UP AND YOUR FEET ACTUALLY GET COLD WHILE YOU'RE DRIVING THE CAR.
