Feel the heated air from your car's A/C vents yet? Well, you may be doing all that waiting for nothing. Your car's heater valve may be stuck, and if that happens, there's no way you'll be able to get through winter driving without freezing to death. So much for your plans to go mountain skiing in Aspen for the weekend. It looks like you'll be stuck at home watching TV or browsing the Internet. Well, here's a better idea-why don't you repair that damaged valve so you could continue your plans to have some fun in the snow? But hold your horses, mister. First you have to understand what makes your heater valve tick. It's basically a valve that lets hot coolant pass through the exterior of the heater core in your heating, ventilating, and air conditioning (HVAC) system. Thus, warm air gets to circulate around your car's cabin. Unfortunately, there are cases wherein the valve sticks, either because of clogging or natural wear and tear. Either way, with the cold weather outside, you're not going anywhere if you don't replace the valve. Anyone with the right tools and some skills can repair a heater valve themselves. You just have to be careful; make sure the engine is cool before working to avoid getting into direct contact with hot coolant. As for the valve-well, just visit Car Stuff.
