1996 Chevy Truck Four Wheel Drive Automatic 250000 miles
The vent for defrost on the drivers side is not opening and when set to defrost makes a loud noise like a hose is off or air is blocked? All the other settings work fine but in this cold weather, the defrost is what I need at -30! I have tried to look in manual and online to see what is involved in getting to the problem but not much luck. Have been told the dash is a nightmare to get behind/under.
