2015 G21 Heater
 

The heater on my G seems to work as it blows air through the defroster fully as well as partially (1/2 of normal or less) through the hose behind the drivers seat. The host at the drivers feet however has no airflow.

Any Ideas as to where to start? I appreciate any feedback!

not to be a smart azz but make sure its actually connected to the blower. Depending what heater is installed some have 2-4 ports i believe but its possible to have the vents in place without being connected
