Yes, it is a 2 speed Blower.

There are two wires which connect to the blower box. They are located under the dash on the passenger side. Very easy access. One wire passes through a resistor(located inside the blower) for the low speed and the other one is hooked directly to the blower motor(high speed). Check to see if the any of the wires have come off of their mounts, a common problem.

Move the wire on the blower, located just under the glovebox where your feet go, from the low speed tab to the high speed tab. Turn the blower on low. If it runs on high speed, the problem is the resistor. To remove the resistor, you have to remove the blower box. To remove the blower box you must remove the dash and dashpad. This is a big undertaking.

The wires are easy to get to. What I mean by under the glove box is in the foot well on the passenger side you will see the blower box located above your feet or Calves. The wires are right there. I'm not aware of any other styles other than the location of the heater valve. I have 4 heater boxes in stock and they are all the same.

The ceramic piece is the resistor. When you hook power to the resistor, the fan should spin but at a slower rate than hooking it directly to the blower motor, i.e. resistance. The ceramic piece is to absorb heat from the resistor wire. You can try to replace the ceramic, but I'm sure someone here has a spare resistor.
