I hope you have the problem fixed by now, but, it is the ABS control under the truck. You need to go under the hood and open the fuse box and disconnect the 60 amp fuse for the ABS, this will turn it off before it burns up. This however will also cause the traction assist off light to stay lit all the time. To the fix the problem you can pay tons of money ($700 or so) to have the dealership install a ABS control and the problem will happen again over time. Or, remove it yourself, go on ebay and ship it off to a guy who repairs them for about $150 and you will never have the problem again. Also, if you wrap your cable ends with plastic and protect them good, you can still drive you truck while the part is being worked on. It takes about a week.

I had the same issue on my 04 Expedition. Like the other posting it is most likely the actuator motor that sets on top of the rear AC unit in the back. However it cost me about $35 dollars and about 15 minutes for me to replace. It is easy to access by removing the top cover that is located on the passenger side rear cover found in the very back underneath the rear glass. Also remove the cup holder which can be removed by prying upward until it pops loose.
The actuator is white and located on top near the front of the rear AC unit and is held in place by three screws. Simply remove the screws unplug connection. To reinstall the new one you may have to turn on the rear AC and barely plug in the actuator until is moves to the position so that it lines up with the blend door. When lined up the actuator should fit right back in place. You could also compare the old unit with the new one and make sure the shaft is in the same position so that you know it will fit back into place. If the new unit does not move when you plug it in to align the shaft, simply select floor or roof position (which is the opposite position you are currently in) on the rear AC control. This should activate the actuator and you can see the the shaft slowly move.
This fixed mine. It is a common problem and my local dealership had them on the shelf. More often they see the front AC unit have this problem but does occur on the rear unit.

Notorious for plugged heater cores. Also updated plastic restriction couplers mounted at heater core available from dealer. Try back flushing heater core. Run engine till its at operating temperature then carefully hold the inlet and outlet hose breifly with heater fan on high if hoses are nearly the same temp then flow is good , if not then core is plugged.

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

I'm just a regular diy'er, no training. Had same problem, 2001 Suburban, front blew cool air when heating, rear heat warmed up nicely. After reading other posts on other boards, took off the the heater hose clamps (make sure you remember which is which) at the firewall. With low pressure garden hose flushed left inlet/outlet first till I got good flow, then the right side, and back to left. Reattached hoses, started and tested. Heat blows just fine. I can't think of anything that could be damaged by this, but check with someone who know something first before trying it on your vehicle, but it worked for me. So far so good.
