Sounds like you need to replace the blower motor resistor. This is located in the ducting just downstream of the blower motor. It controls the lower speeds.

Can you provide a more specific location. A picture would be great. Do I need to take the blower motor out to get at the resister? It's just not obvious where it is located.

No. You don't need to take the blower motor out. Blower motor resistor is located right under the dashboard.
If you cant find it or don't know which one is the resistor. Let me know. I'll email u a pic of my old resistor
I replaced resistor for my nissan sentra 1994. Works great now.
