Question about 2002 Ford Thunderbird

Open Question

Where is the FEM on my 2002 Ford Thunderbird located?

I am having intermittent issues and the common denominator is the Front Electronic Module (FEM). I suspect loose pins, connector or corrosion on pins. I just don't know where this module is located in my car.,

Where is the wiper relay located on a 2000 Ford Windstar

There are two relay's located in the under hood fuse / relay box . Windshield wiper on / off relay an windshield wiper speed relay .Both relay's are controlled by the FEM - front electronic module . The prudent thing to do would be to take to a qualified repair shop that has a professional type scan tool to check for DTC'S - diagnostic trouble codes rather then play a guessing game . Changing parts that don't fix the problem . The wiper switch is a input to the ( FEM ) when an input is seen the (FEM) then energizes the relay's .

Why when I turn the motor off, the headlights and motor blower come on? (2000 Ford Windstar Lx)

The FEM (Forward Electronic Module) is defective....See image #1...This necessitates a trip to the dealer in that replacement requires a Ford Diagnostic Tool...See Removal and Installation instructions below...You may find one on EBay...

Front Electronic Module(FEM)
Removal and Installation

CAUTION: Prior to removal of the FEM, it is necessary to upload module configuration information to a diagnostic tool. This information needs to be downloaded into the new module once installed..

Disconnect the battery ground cable..
Remove the instrument panel lower steering columnopening cover.
Remove the bolts. Thumbnail 1

Remove the instrument panel opening cover reinforcement.
Remove the bolts. Thumbnail 2

Remove the front electronic module(FEM).
Disconnect the five electrical connectors.
Remove the three bolts. Thumbnail 3

CAUTION: Once the new module is installed, it is necessary to download the module configuration information from the diagnostic toolinto the new module.
To install, reverse the removal procedure.

Cost is high, Around $500

02 thunderbird, car does strange things the wipers won't work, the drivers power window, horn, instrument cluster lights, and the door chime and drivers door indicator stays on

Since most are unrelated. Check the fuse for the wipers, replace the motor. Replace the regulator for the window, Check the fuse for the horn, most likely it is the steering wheel button bad, if you have lights for the radio and A/C, pull the IP and check wiring and plugs for corrosion. Replace the door latch and the light and chime will stop.

All the thing's your having problems with are controlled by the computer's an communication network . (FEM) - front electronic module , insturment cluster , (REM) - rear electronic module. etc... It's probably a loose ground connection somewhere . The headlamp switch is a electronic input to the insturment cluster , the insturment cluster is hooked to the SCP - serial data network . The insturment cluster electronic's (computer ) microprocessor sends a message to the (FEM) to turn on light's , the front electronic module will then suppy a ground to the headlamps circuit turnning on the headlamps. Samething for the wipers an turn signals an horn too .

From looking at a wiring diagram i would look at ground connection G-304 . Do you know what a body ground is ?
This ground is located How to troubleshoot headlights intermittently on and off with headlights...

1down vote Basically your headlamps are controlled by a computer. The Front Electronic Module (FEM) to be exact. The FEM grounds the headlamps when it wants to turn them on. This system was an early Multiplex design that reduced wire and total circuits where the modules communicate on a single serial line, now referred to as the CAN Bus (Controller Area Network). You will likely need a scan tool to diagnosis the car, and not a cheap one, but a professional model. You many even need a factory scan tool, though I doubt if for a Ford. Outside of security theft deterrent systems they allow the aftermarket professional scan tools to access their systems.
So where do you go from here? With or without a scan tool, the grounds are a good place to start.
G303 are the main ground for the FEM.
G304 is connected via C179 (C means connector) and through S139 (S means splice)
G304 is located behind the LH cowl panel C179 is located behind the LH side of the instrument panel S139 Dash panel to headlamp junction, near T/O to C192 Front Electronic Module (FEM)
You can see the FEM, G304, and C179 in the picture below. Outside of checking the connections and wiring there is not much you can do without a scan tool.

1996 thunderbird 4 6 power brakes and power steering fades in and out while driving"

This may be your problem.

FORD: 1994-96 THUNDERBIRD LINCOLN-MERCURY: 1994-96 COUGAR ISSUE: Steering efforts at low speeds may intermittently increase to the heavier for highway setting on some vehicles. This is due to electrical "noise" from the Vehicle Speed Sensor (VSS) being picked up by the Electronic Variable Orifice (EVO) module. The EVO module then interprets this as an increase in vehicle speed and reduces the steering assistance to the heavier for highway level.
ACTION: Replace the EVO module with a new module that has improved filtering for electrical noise. Refer to the following Service Procedure for details.
SERVICE PROCEDURE Replace EVO module (F6SZ-3F712-BB). Locations are as follows:
  • On 1994-95 vehicles, the EVO module is located under the package tray in the trunk.
  • On 1996 vehicles, the EVO is located under the heater blower case on the passenger side.
Refer to Section 11-02 of the appropriate year Thunderbird/Cougar Service Manual for additional diagnosis and repair information.

WARRANTY STATUS: Eligible Under The Provisions Of Bumper To Bumper Warranty Coverage
OPERATION DESCRIPTION TIME 960402A Replace Electronic Variable Orifice (EVO) Module - 1994-95 Thunderbird/Cougar 0.5 Hr. 960402B Replace Electronic Variable Orifice (EVO) Module - 1996 Thunderbird/Cougar 0.3 Hr.

My 2001 jaquar s-type every two weeks car won,t start new batt,nothing draining elect sys,alt ok,car will not start if you jump battery,car will start if you put jumping cables on alt and ground other to...

The S Type is similar to the Lincoln LS.
These are TSBs that address battery drain on the LS.

Partial TSB
Article No.
Publication Date: APRIL 30, 2002
ISSUE: Some vehicles may exhibit excessive electrical system current draw which could result in a discharged battery and a no crank condition.
ACTION: Use the following Service Tips to monitor the vehicle electrical system for excessive battery current drain and repair as needed. Refer to the following Service Information Tips for details.
SERVICE INFORMATION Having a firm grasp on the design and normal operation of the electrical system will aid in properly diagnosing and repairing any faults with electrical components and/or circuitry. When the vehicle is at rest (ignition key turned off and removed), some amounts of battery current drain will be present since many of the modules and electronic components in the vehicle require this to sustain memory and system monitoring. The Powertrain Control Module, Antilock Brake Module, Electronic Automatic Temperature Control Module, Front Electronics Module, Rear Electronics Module, Driver Door Module, Instrument Cluster Module, Roof Opening Panel Module, Heated Seat Module, Driver Seat Module, Cell Phone Module and Vehicle Emergency Message System Module all have power supplied at all times for this purpose. Many of these modules monitor activity and communicate with each other through the Standard Corporate Protocol (SCP) Link. When the ignition key is first shut off and removed, the vehicle is exited and the doors are closed, the electrical system goes into "stand-by" mode, where the Rear Electronics Module (REM) and the Front Electronics Module (FEM) keep the System Switched Power (SSP) relays activated. After a minimum of 45 minutes, the REM and FEM will power down to prevent battery discharge. Power down mode occurs when the REM and FEM "time out" and release the ground on all 4 (four) of the SSP relays. The SSP relays are wired in a fashion in which they are either all on or all off. In other words, the SSP relays cannot be operated independent of each other. If power down does not occur, because of a system fault or errant SCP Link activity, the REM and FEM will remain energized along with the SSP relays and the other electrical devices that they provide power. The REM and FEM provide power and ground to devices such as exterior/interior lighting and many of the body modules in the vehicle. The Wiring Diagrams Manual may be referenced for additional information on the SSP relays, the REM and FEM, in Sections 13 & 59. Once the REM and FEM enter power down mode they will not energize the SSP relays until they are commanded to "wake up" by one or more of the following commands:
  • Key Fob Activity (Any Command)
  • Door Ajar (Any Door)
  • Luggage Compartment Ajar Switch
  • Drivers Power Seat Switch
  • Power Tilt/Telescopic Steering Column
  • Headlamps/Park Lamps On
  • Key In Ignition
  • Key On Ignition
  • Anti-Theft Hood Switch
  • Brake Pedal Position Switch
  • Memory Seat Switch
