Hey guys I have a 98 expedition XLT with the 5.4 the a.c. worked great front and back it changes from floor to dash etc fine. However when i try and change it to heat the back works great, but the front has cool air coming out and no heat. I don't smell antifreeze when I have the heat on. I assume the blend door is working properly since the rear has heat. Unless there are 2 blend doors? Where should I start with diagnosing this issue
