Can anyone point me in the right direction?

I need to replace the ac blower motor on my 05 Silverado. I'm pretty sure it's the problem due to, when I turn on the ac I can hear the compressor power on and the engine idles down, as well as, the ac button lights up, but whenIturn the fan control on nothing happens. It started fine one morning and then the fan started and stopped a couple of times, then nothing.

I was hoping to find some technical instructions or something like a how to replace iton the internet, but as of now no luck. Any help would be greatly appreciated!

 

I doubt its the blower motor..its most likely the blower resistor...look at it..if it and the connector are melted,you need to replace both
