2015 gmc Sierra Denali 6.2 blower motor not blowing strong

[Adoomie Abdallah]

My blower motor doesn't blow hard at all, maybe medium power at most. My controls work, it goes from low to high but compared to my other 2015 2500, it doesn't even compare. 

 

Replaced the blower motor, same issue. Bought the resistor from rockauto but can't find anywhere online that shows its location or how to access it. I read on another topic someone said it's built into the blower motor, but when I looked at the new blower motor and resistor, it isn't a part of the blower motor assembly. 

 

Any help is much appreciated 

 

Resistor looks like this

Pretty sure the K2XX trucks do not have an external resistor, it is built into the body of the blower motor.
