Come with an owners manual?

The 90's had a weird totally auto climate control. I'm not familiar it's voodoo.

Ok I am lost here too.... What kind of climate control system does it have auto or manual?

If its Auto, then the car has to reach operating temp, before the climate control unit will let it blow out of the dash vents. It will blow out of the floor vents and the defrost first. If that doesnt change then you have a vacuum leak somewhere in the dash. Check all the lines to the climate control Module. Make sure none of them are split or cut. You will have to take apart your dash to do this. LOTS of phillips screws, dont lose them, most will go anywhere but if you lose one it will have a rattle from the dash area. Past that I cant tell you much other than the word sence, is not spelled "cence".

If it wont blow hot air. Try purging your coolant system, if you have air in your heater core it wont get hot. If it doesnt get hot you wont have heat. So try bleeding the air out of the coolant system.
