2001 prizm heater fan speeds

I've lost all but the highest speed on my ac/heater fan in my 2001 prizm. Ronnyvous mentioned in another post that the resistor pack is to blame. i don't have a manual, so could someone tell me where to find the pack? thanks!

The part that you are looking for is the healter blower resistor. It is about $41 and it is located under the blower. Just take of the glove box and you will see. The whole process is about 15-20 min
