What would cause the heater fan to run with the key in the off position on a 1997 ford f150 truck also the warning sealbelt and air bag light stays on only when the truck is started?

The fan runs at a very low setting any time the ignition is on. If the SRS light is staying on after the truck is started, then you have a problem with the air bag system. The seatbelt chime should go off once you put on the driver's belt. If not there is a problem here, possibly bad ground connection.

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.
