No. Bowtie is AC only.
There are other vents for heat/fresh air. |

Heat comes from the footwells - don't believe there are underdash vents

Thanks for the confirm. Looked like the Bow Tie tube went straight to the Evaporator.

I doubled airflow to the center by blocking the long runs to the side vents used only for A/C with very marginal cooling effect.
Removed the ductwork on top the evaporator and blocked the side exit to the driver side vent tube. ![]() ![]() Then under the dash I removed the long hose to the passenger side vent. ![]() Chopped it into pieces and painted it black. ![]()

Changed that passenger side vent routing to exit center under the dash with a three inch hose and a piece of PVC transition on the end painted black.
![]() Now with the bow tie still in place but drilled up a bit for more airflow and a second large under dash center hose I get dramatically more air flow in the center of the cabin. No need for spendy larger air flow fans in the evaporator box. Plus the passenger dollies like the cold airflow at their knees. Haha its directable!
