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.

That's video of inside my dash, no clue where the resistor should go. Also here's a picture of the blower motor open, doesn't look like any resistor is built in but I'm not sure, the screws have solder in them so I can't really pip them out right now but I don't think there's a resistor in there.

Maybe this will help? Make sure to look at the diagram towards the end of the page.

Throwing motors and blower modules at it...have you bothered to check the cabin air filter to see if its dirty or severely restricted?

That’s what I was fixing to say too we checked to see if my uncles sierra 2500 hundred filter was dirty and sure enough it was packed to the brim once we changed it and put a new one on the air was blowing so much faster then before
