Answer
Hey Tim:

Easy fix! this car needs a blower motor resistor. Its easy to change it's on the right side of the dash under the glove box it's just behind where the fan mounts to the bottom of the HVAC module. This is a dealer only Item I belive. The resistor burns out and the lower speeds quit. It will not be ling before speed #3 doesn't work either. It's about a 15 minute fix. The one you take out may look different than the one in the car now. Don't worry about it they have changed the design multiple times in the past few years. Good luck :)
