My fan blows, but there's no heat from front vents until RPM's are up. Stop at a light and vents blow cold air again. Sounds like vacuum problem? Also seems to be no hot air from rear vents.

Actually, it sounds like low coolant. Have you checked to see if the engine coolant is full?

Let me know.

That's exactly what it was. A friend also had the same problem with his Ford, and I checked and filled the day after I posted. The guys who change our oil were supposed to be checking this. Guess we won't be going back there again. Thanks!

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
