[Vwdiesel] the core of the Problem?

[mikitka]

Sounds like the foam on the divider door is gone.  It happened to my 91
jetta diesel. The divider door has holes in it so it will not separate the
air and allows the cold air to mix with the heat off the heater core.  I
took my duct work apart and was able to put new foam on the divider door
without taking it completely apart and now I have comfy heat, before it
would barely blow warm air.

Here is a good site for information on the heater door.

My guess would be either a too cool thermostat or a stuck open t-stat.  Or
try back 
flushing the heater core (insert garden hose into the return line and run
water out the 
inlet line) and make sure the heater valve is opening fully with the dash
control.
