Kia sorento AC only working full speed

Symptoms: I had a problem where the air condition in a Kia Sorento will only blow air when the fan speed is set to the maximum. The controls show the fan speed to be on slow and medium speeds but only the slightest air pushed through the vents.

The fix:
The problem is a bad blower resistor. This controls the speed of the blower. It is located behind the glove box, on the blower assembly. The glove box comes off by opening it and pulling it upward, off its hinges. The resistor is held in place by two screws. A very short screwdriver or a socket set with phillips head has to be used. In my case I have a 3 pin resistor so I had to get a similar part. The A/C will work even if this part is removed from the car but with the same problem of the fan only working at full speed. I bought a replacement (Wells JA1394 HVAC Blower Motor Resistor) for approximately $50USD and was able to change it out myself. I have a 2003 right hand drive Kia Sorento, 2.5L turbo diesel. The new part has a completely different metal section but the plastic and connection are the same. There is a side by side picture below. It works as expected.
