Default '98 Cadillac DeVille No Heat

Have a '98 DeVille that puts out no heat. I was told by a buddy that it could possibly be the "Heat Control Solenoid". I have know clue where this could be at. Anyone have any idea?

Not real familiar with that car, but I assume your engine is getting up to heat. In that case I would check the air mix actuator. On the cars I'm more familiar with this is on the passenger side under the dash near the center. If this is not moving there will be no heat.
