I just replaced my heater core on my 97 Buick Skylark 3.1 L with 167k on it and the blowed motor sounds like it is barely on, there is no air blowing out of vents. I am getting heat and A/C on freeway, defroster is working but not at high setting. Does this system run by vaccum or could it be the resister gone bad? Steve

High speed is the only speed that is not wired through the resister. Check the 30 amp fuse marked "HVAC blo mot" in the engine compartment fuse box. If it is good, then check the relay.
