I'd start with the basics such as checking your coolant level, feel the heater hoses to see if they're both hot (this will tell you if coolant is flowing through the heater core), check to make sure the vacuum line going to the heater control valve is hooked up and that the vacuum line isn't cracked or broken. After that I'd probably check to see if your blend door actuator is moving when you change from hot to cold.

the blend door is not opening and closing its cold all the time everything else is fine

Sounds like you either need a blend door actuator or the blend door is broken.
