Did the heat work before they got under your hood or did you just not notice it because it's hot outside?

[VerseOne]

im not sure if it worked before never tried it just bought it two days ago

these cars have a lot of issues with the control knobs. it doesnt pull the right vacuum so even though the inside gauge says heat, it may still be on the a/c setting. i had the reverse wrong with my car. just fixed it today. bad vacuum hose in the engine compartment.

Yea like bsudak said it's probably a vacuum leak/bad hose. There's also a little valve to the right rear of the intake manifold that has a few vacuum hoses on it...sometimes that goes bad and will cause what you're talking about. It's a quick fix but if the dealer is going to do it then all the better.
