aw c'mon ya big pansie. how long have you lived in Michigan? just kidding...
could there be some kind of blockage in the heater core? go back to the place that did the work and see what they have to say about it. i'd let them fix it.

I feel your pain. I have a 93 with the exact same problem. I just had my AC replaced last summer, i noticed it after that. Not sure why. Some one chime in w/ answeres please. the fan works fine. it will get hot eventually but doesn't blow out the super hot like other cars.

make sure that the coolant level is topped off, and make sure that the heater hoses aren't kinked or restricted.
