    Can you not feel any are moving or is it just not warm?

Could also be the fan switch, just pull the dash apart and find the hot wire going to the switch, then check and make sure you have 12 volts with a volt meter, with the key on of course, if you do then jumper that to one of the wires going to the fan, if that works its your switch, if it doesn't its the motor. If you don't have around 12 volts for the hot you may have a short or just a bad wire. Again use the volt meter and trace that wire back to its source until you find the problem. Hope this helps!!

Heater only works while on the freeway

Sounds like either low coolant or air in the cooling system. Either you need to bleed air out of cooling system or repair possible leak in system. When there is air in cooling system and it goes into your heater core, heat is not transferred to the air blowing out of your vents.

Heater does not blow hot only cold air. Every so often the heater blows hot . When driving on freeway the heater works sometimes but turns cold when at red light.

Check the radiator level, if it low the hot coolant will not reach the heater. Second may be the water pump, as it wares the clearance increases and the efficiency goes way down and it cannot pump the coolant unless the engine revs are up.....

I would check your thermostat. Even replace it if its not that expensive. Hopefully its not a heater core. Good Luck..
