Hello, I see a lot of ignition switch problems on the Ford portion of this site. Its an inexpensive part and can shut off all of the items you list. If it stays on it can kill the battery too!

Double check the Cruise Control for the Recall with Vin#. It had a short built-in, but after the Recall fix some vehicles had problems with the electrics on the 4x4 and even brake lights.

There were some problems with the starter end wiring off the main loom. Have your battery checked for shorting. Check main chassis grounds, I believe there is one on the frame under the passengers front door. Please let me know what you found and I can pass ot on.

Wiper control module location on a 2000 f250


Did you check the wiper relay's in the under hood fuse box ? There are two ,wiper run/park relay & wiper high low relay ! Also ,did you check fuse's ? fuse # 11 - 30amp location cental juction box . The wiper switch is a input to the GEM module . Generic electronic module . The module in most cases isn't the problem ! Learning how to test these electronic systems is , people do not know how to test so they just replace parts . What they should do is take the vehicle to ford certified Technician who has the knowledge and testing equipment to find an fix it .

The generic electronic module (GEM) receives inputs from the following:
  • multifunction switch
  • anti-lock brake control module (vehicle speed signal [VSS])
  • ignition switch

I bought a 99 ford mustang without a radio installed yet there is an aftermarket radio in the back seat, the wipers are not working and i have checked the fuses they appear fine, i also pulled plug source...


Defective switch or wiring between switch and motor. The 1 wire that does have voltage is for the park function. I would pull the switch and test for voltages going into the switch, with ignition switch on, then turn the wiper switch on and see if you have any voltages coming out.

Generic Electronic Module (GEM) Removal and Installation
  1. > CAUTION: Prior to removal of the generic electronic module (GEM), it is necessary to upload module configuration information to the diagnostic tool. This information needs to be downloaded into the new module once installed. For additional information, refer to Section 418-01 .
    Depower the supplemental restraint system (SRS). For additional information, refer to Section 501-20B .
  1. Remove the radio chassis. For additional information, refer to Section 415-01 .
  1. Remove the center instrument panel finish panel.
    1. Remove the screws.
    1. Remove the center instrument panel finish panel.
    • Disconnect electrical connectors.
    • Module Controlled Functions The multifunction modules consist of the following:
      • generic electronic module (GEM)

Mazda 626 1999 with electrical problems. Replaced alternator, battery checked out, electrical quits while driving.


When you say everything goes dead are we talking all lights, radio, wipers? If so, main power or ground cables bad or fusible link. If just engine, check coil, ignition module, crank/cam position sensor.

Power winidows, wipers, dome lights not working on 1998 explorer


This could be a combination of electrical issues, although i feel that the timing is coincidence in this case. When the combination is elec. windows, wipers, and dome lights this is indicative of the GEM module located behind your radio. The GEM (generic electronic module) is an electronic body control module that regulates electrical flow through a number of accessories.

These factory module boards are notorious for acting quirky by failing to ground intermittently until failing completely. I would be cautious in replacing ignition switches, locks, etc. as the issue can be also compounded by corrosion of the main battery ground wire in the engine compartment and which can cause frying of your under dash wiring into the main wiring harness which can get expensive (i speak from experience having had the exact same syptoms). My issues were that these symptoms occurred only in full ON. When in key BACK ACC mode, they disappeared.

New price for one of these modules is around $280-$300 and easily replaced.

Good Luck
