Thermostat??
OK, all you guys up north, don't laugh -- my 86 6.9's heater is pumping out just slightly warmer air than the outside temp. Hasn't really been a problem until the last couple days when we've seen morning temps at or below freezing.
Could this be a thermostat problem?? How hard is it to replace?? From doing a search on this topic, sounds like the only replacement part would be a Ford thermostat and not any autoparts store brand replcement.

Hi all,
'hope you don't mind me 'piggybacking' on this thread, but I have a similar issue with my 88 7.3 The gauge usually runs about 1/4 of the way up from cold , but it takes a very long time to get heat from the heater and it doesn't seem to get as hot as a few years ago when I bought the truck. I'll try the things suggested already, but I was thinking thermostat too.
Thanks

How warm are the hoses to and from the heater core?
Could also be something holding the blend door open, letting in to much outside air.

I checked the blend door, appears to be opening and closing as advertised.
If the one heater hose is hot and one is cold could it be the core??
