My heater control inside the vehicle only works on the 4 & 5 setting. I get no air at all on settings 1, 2 & 3.

Hello,

It does sounds like a faulty blower motor resistor. Which is a very common issues with these cars. The resistor is mounted on the side of the blower motor. See below for the replacement procedure of the resistor.
