"Relay," maybe? The highest blower speed on older manual-control cars used a relay, so that the dashboard fan switch wouldn't melt under the load, but I don't think that'* true in your case since you're hearing the fan blowing already; when the high-speed bypass relay failed on older cars, the blower would go completely dead when HIGH was selected.
Anyhow, I'm wondering if you don't actually have a duct switching problem instead, so the blower is moving air but the air can't get into the car.
1) Do you have the electronic (i.e. vacuum fluorescent dash display) or the manual-**** controls?
2) Aside from the airflow being weak, can you still direct it to the various ducts? (i.e. windshield defrosters; dashboard vents; floor heater outlet) If the dash display indicates that the dashboard vents should be blowing air, but it'* coming out the defroster or heater ducts instead, you've lost the vacuum needed for the duct controllers. Check the black plastic reservoir connections under the hood on the firewall next to the master cylinder brake booster.
3) So does the car start now, or is that still screwed up as well? If so, maybe something'* left disconnected on the firewall fuse/relay panel. (Did you remember to reattach the large power cable to the bolt at top center of the relay panel?)
