Heater Trouble

[sprman4lissa]

Hello all i'm new to the site and Expedition... I have a 98 with the 4.6 4wd and it's all stock.. my problem is that i have heat in the rear but blows cold air in front.. when i change the temp control i can hear the difference in the way air blows if that makes sense.. Was hoping someone can point me in the right direction of where to start on trouble shooting... thank you!

Plenty of threads already on here concerning your problem and a few of them being very recent.....
1) Check temp of both lines to the front heater core once up to temp, both should be hot to the touch
2) Check coolant level & condition(trash)
3) Check blend door operation - may have the broken pivot problem or failed actuator.
