ExplorerLyon · 10-04-2018, 05:59 AM

The blend door is only fully closed (heat) when I set the temp to HOT, regardless of selector for defrost, center or floor.

When I drop the temp one notch to 85, the blend door moves and too much cool air starts to come through. If I manually select the diverter to the CENTER vents, door closes and I get full heat. Setting the diverter to defrost or feet, the blend door moves and lets to much cool air through.

In other words, I get full hot heat, but only when I select the center vents or temp at hot.

Both blend door and divertor door (don't know if those are the right terms) fully move. I previously replaced all the foam on the doors and they are fully taped up and have full movement.
