typ44 evap flap question

[JordanVw@aol.com]

hey, all.. i finally got my a/c to blow out my dash vents today on my '86 5kT 
(now that winter is almost here :<)  i installed that little steel C clip fix 
thing over the remainder of the broken evap flap vacuum mount, and got it all 
backtogether (i ended up heating a finishing nail up w/ a torch, and melting 
the screw pilot holes in the plastic because there's NO way you can get a 
drill in there..) it appears to work well.   anyway, heres my question - 
when the climate control is off - is the evap door supposed to be open to the 
engine compartment? or closed?  (its open now) i always thought it should be 
closed...i pulled alot of leaves out of there.  

thanks in advance-
