86 5KTQ - how does your heater blow?

[Livolsi, Stephane]

Hello all.  I am trying to sort out a poorly functioning heater in my 86
5KTQ and I hope some of you with properly functioning systems can pipe in
about how exactly your vents blow.

Specifically, should the dash vents be blowing hot air?  I get hot (actually
just warm) air out of the dash defrost vents and the foot vents, but never
out of the dash vents.

In the summer, I did get good blasts of cool air out the dash vents.

Thanks in advance for your help
