Generic Electronic module.

Where is it and what does it control? Tach gauge, oil and battery gauge quit working along with the radio, cruise control. New battery and alternator and battery will not stay charged. Any suggestions?

The gem is behind the dash in the center, behind the radio. It controls whipers, anti theft, 4x4, cargo lamp, insterment cluster, plus a few other things. Hope this helps.

The guages do not go through the GEM, neither does the radio or the cruise.
Go to this link for a complete description of the GEM functions.

Several options exsist.
1. What was happening when these all quite working? All at once, over a period of time, alternator went and then everything else.
2. alternator charges battery-if that's new and battery goes dead then look for improper hook-up or possible short circuit on/with alternator.
3. check your voltage regulator for defect.

1. Have you looked at your owners manual for location of the cruise control fuses? 2. Same for the tachometer? 3. Do you live in a wet area with alot of rain? Next chance you have, get some electric cleanout spray from NAPA spray into all cruise control connections and tach connections. 4. Check the recalls from Ford there have been issues with 99 cruise econtrol systems.

Electrical system goes crazy!!


Dirty Power and Ground connections. Working from the Battery, disconnect and clean all joints, along the Harness to the Main power box, and do the same in there.
It is a Ball acher, but it will fix the problem.

The cruise control just quit


By removing the ABS brake fuse you are disabling other components as well. The ABS fuse supplies voltage to the brake switch that tells the ECM and ABS module the the brake has been applied. If neither of the modules can see the brake switch the cruise control will be electrically disabled. You need to reinstall the fuse.
Let me know.
