I know its not a engine problem like the rest of these but I need some help I have a 07 f250 and the blower works fine and it will switch from floor to vent just fine but when I turn it to heat it stays blowing cold any one have any ideas where to start or what it could be

 

Could be your heater core, no antifreeze, climate control module.

 

Well the heater core isn't leaking and my coolant level is fine

 

Mines doing the same thing. But the air is hot while I'm on the throttle. It is losing coolant also, so I'm thinking it's my heater core. But I can't find anywhere that it's leaking

 

Feel the heater hoses and see if you are getting flow through to heater core. . .place to start. If core plugged it won't get as warm.
