Have Dodge Dakota 2005 Quad cab 4WD 6cylinders
Have a similar problem with the 4WD light.
Started a couple of months ago. It would flash on the dashboard, stay on few minutes then go away.
After two weeks I noticed the 4WD shifting on its own even after the truck has been parked for few hours.
Seems that opening the door to retrieve something triggered it. Any of the 4 doors.
A week later it started shifting into 4WD on the FWY, I would pull over, shut the truck off then restart before I can drive again.
To stop the shifting I pulled fuse #40 out of the box, that did the trick, been driving it like that for about a month.
With the fuse out, it does not shift but the light comes on after driving 1/2 hour or so. It stays on until I stop and park.
The next time I get in, the light would be off, goes 1/2 hour driving then the light pops back on. No shifting just the light.
I disconnected the A/C switch, still did it's thing.
I tried to replace the transfer case shift motor but could not take it out of position unless the engine main bracket is taken out.
Believe me, not an easy task. Extremely poor design so I gave up on changing it.
Now, after reading many posts I'm beginning to think it's the FCM (front control module), mounted onto the fuse box.
Dealer wants $800 to replace it.
My question is: Can the FCM be replaced by me?
Does it need re-flashing?
Any help, advise or information is appreciated.
