'864kQ heater stuck on

[sabuti@nyc.pipeline.com (Sabutin)]

--Thanks for all the help. My next problem as I shake down my new '86 kQ is
that the heat comes up full blast out of my side vents +/or
defroster/footwell vents no matter where the temp control is set. The AC
works to some degree when it's turned on (colder from the center vent than
the sides), but I'm sure it would be cooler if all that engine heat wasn't
being routed toward the vents. Has someone misrouted the ducts that are
supposed to send outside air into the system?
