Having problems with your 2004 Ford Expedition ?
Front heat works, but rear blows cold air only
\015 2004 Expedition: The front heat works, but rear blows cold air only.\015
With your front heat working the most likely cause for the rear heat not to work is that there is an obstruction in the line that is preventing the warm coolant to get to the rear heater core or the rear heater core itself is plugged and not circulating. Another possible cause could be low coolant level where the system has enough coolant to provide the front system with enought warm coolant but not the rear system. Hope this helps
