Using 05/06 pcm in 03

will a pcm out of a 2005 or 06 expy work in an 03? yes, i know the engine and transmission are entirely different and will not work, my main concern is if it will play nicely with the modules on the truck like the cluster and bcm and security module. i know they are technically all 2nd gens but i dont know if there were any major changes or revisions to these subcomputers that would make them incompatible. the reason i care is because hptuners only works on 05+ expeditions and i dont think it will ever be supported, so this seems like the only real possible solution to self tuning this thing ..read more

Hello, 2006 Expedition 5.4 3 valve with 179,000 miles. Lost overdrive. Shifts fine from a stop; 1st, 2nd, 3rd then slips when it goes into O/D. Like it’s in neutral. Manually downshift to 3rd and it runs fine. Turn of O/D, it drops a gear and runs fine. No DTC codes. I’ll check fluid level in the morning. First time this happened. Any suggestions? Basically feels like I lost O/D. A filter and ATF fluid change was on my to do list, would that help? I have a bottle of Motorcraft Friction additive for transmission/ differentials. Would that help?? mike ..read more

Window motor replacement

1999 Expedition XLT 4x4 5.4L Drivers side window is up and does not function. When pushing the window button I hear the relay clicking. There was none of the typical grinding noises when the regulator goes bad. I assume that it is the motor only. All the other windows work. I understand it is possible to change the motor without removing the regulator. I know I will need to tape the window up. It seems that I saw something about the regulator spring releasing when the motor is removed. Is the correct? If so how do I avoid that happening? I have replaced regulator/motors on too many occasions ..read more

2006 Expedition - Electrical Issue(s)

I realize electrical issues on a vehicle can be hard to narrow down, but here's hoping some direction can be provided on where to look. I am an engineer and experienced troubleshooting electrical issues, as long as I have good information and schematics to follow. Our 2006 Expedition recently experienced numerous anomalies that seem unrelated but could be tied together somehow. First, the rear hatch window unlatches whenever the A/C is turned on. The headlights in the Auto position will also turn on, even in daylight, when the A/C is turned on. Attempts to lock the doors via the door lock sw ..read more
