Are you talking about two separate switches?
The rear defrost switch might have corroded contacts or a bad spring mechanism. The factory manual recommends you pull off a few covers and drop the steering column to get to the defrost switch, but I found that some careful prying at the top and bottom of the defrost switch where it meets the dash with a knife point or thin flat screwdriver will get it to pop out. If you are adventuresome, pop the switch open and clean the contacts (look out for a flying spring!) , otherwise get one from the dealership or friendly local junk yard.

If there is power to the off switch for the heater is the switch gone?
If you are talking about a wall switch for the heater, check to see if the heater has its own internal thermostat or switch as this might be in the off position and not allow the heater to turn on. If you are talking about a switch on the heater itself, then yes in all probability the switch is not working.
In your 1997 mustang the air is blowing through the defrost Why isn't it blowing through vents?
this one is easy your switch the controls the vents is not working there is a flap the closes the defrost vents so that it goes through the other vents or there is a vacumn line that is controlled by the switch, and its leaking. The vacumn line is usually on the engine side of the firewall. It is a very small plastic tube comming out of the middle of the firewall at the top and it connects to a junction with other vacumn lines. See if any of them are disconnected.
