Sounds like a possible short in the wiring somewhere

Does the fan stop running or do you lose heat? Try to be as specific as possible.

It blows just fine while I'm driving but as soon as I step on the breaks it starts to blow cold air. I hate red lights & stop signs

Okay. The fan continues blowing, but it blows cold air rather than hot. Make sure the coolant level is full and let me know what you find. NOTE: When the engine is cold, check the level in the radiator and not only the overflow.
