2002 Denali, front fan/blower not working.

[Brian HCM#1]

Hi all!

I can not figure out how to fix the fan front heat/AC in my wife's car. I've replaced the front control panel and just replaced the blower motor today and still no luck. What else can it be?

check the fuse? did you check the relay? did you check the resister next to the blower motor? are you getting power to the blower motor?

The fuses are fine, I just replaced the resister module to blower. I did not check the relay, where would that be? I used a test light and found no power to the blower motor module (don't know if that is an accurate way to test for power). This one has auto climate control. Could there be other things, I'm not seeing here?
