Question
QUESTION: 2002 Dodge Grand Caravan - Heater worked fine yesterday. Today NOTHING. Any idea where to start?

ANSWER: HI Robert

Not sure what you mean by nothing.  Is it not heating but blowing air or is it not blowing air at all hot or cold.

QUESTION: NO air at all. Thanks Candido.

Answer
It sounds like your blower or resistor is bad.  First check if blower has both ground and power.  If it does then replace blower.  If you are missing ground then your resistor or blower module is bad.  If you have ground but no power then check your fuses.  Good luck and let me know.
