its located on the heater box in that one right behind the glove box ,you can identify it because it has a small wiring harness going to it and is held on by two 8 mm bolts,their easy to replace,and only cost about 15-20 bucks depending on where you buy them at,and it is the resistor that cause's that to happen on those when it goes out all you have is high speed or off,good luck.
