GEM replacement then flash upgrade?
Problem: Rear wiper no workie. No bad fuses. No bad relays. No bad motor.
Problem: Washer fluid low indicator on all time.
Troubleshot down to the GEM that all these functions are controlled through. Then read on my service manaul CD that if I was able to get the GEM out and replaced that I would need some special gizmo and cable to "flash upgrade" it.
That would seem to limit this repair/replacement to the dealer and that sucks!!
The GEM is located on the "back" of the interior fuse panel and is a *bear* to get to and to get out.
Any suggestions for me would be greatly appreciated.

You're supposed to "move" the programming from the old GEM to the new one when you replace it but I've done lots without doing that.
I think you'll find instructions for replacing the GEM in the F-150 forum.
Basically you remove the dash trim under the steering column, remove the 2 big connectors off the back of the fuse box, unbolt the fuse box/GEM, then unplug the connectors and remove the fuse box/GEM.
