The door that closes off the cabin and the door that opens the evaporator
box to outside air share a hinge assembly in a fixed relationship. That
is, the arms the doors are fastened to come from the shared hinge are
molded into a nonchanging position so that when the cabin door is open to
allow cabin air into the evaporator box, the evap door to outside air is
closed, etc. The return spring is intended to close the cabin door. If
it's hanging from the inside of the box, its plastic anchor on the door is
broken (not very common) or the "hook" end of the spring is broken. If
it's hanging from the plastic anchor on the back of the door, the plastic
bar inside the box has been cut through by the spring or the spring end has
broken. The most common failure is for the spring to cut through the
plastic bar. The easiest fix is to fold a loop of light metal over the bar
and put a hole through the metal for the spring to anchor in.
