The heater in my car doesn't work. Air conditioner and other controls work fine. Can I fix this myself or does it need to go into the shop?

Often the heater tap fails, it is located under the inlet manifold if the vacuum line is off the tap should be in the on position, also check that the heater core is not blocked, start here.
