No heat from front vents of 2005 Chevy Suburban

I should clarify - the air that does come out when RPM are up is warm to whatever temp is set, the problem is I can't get any change in the amount of air blowing from the front vents even w/ the fan set to high

is your blower running and is the air the out side temp

air temp is set to 80-90 in the mornings and is set to come from the outside. i don't hear the blower at all regardless of where the control is set

did you check at the blower to see if their is power to it

haven't torn into it yet - trying to gather a list of everything to look at

First start with checking the fuse. Then look at the plug where the blower motor resistor plugs into the blower motor. The plug sometimes melt and end up shorting out the blower motor and blower motor resistor. If the fan only works on High then it will be just the blower motor resistor. All of this is located behind the glove box near the firewall.

I am having the same issues, rear blows normally, front heat come out but variable to speed I am traveling.
