I think the REM is located on the right side underneath, near RR wheelwell (or is that the trailer tow module????).

Don't have the tow package (that I know of)

Now that I think about it, I do remember reading something in a Ford Bulletin about the jack (which sits
inside the right rear quarter trim panel) sometimes pinching wires for the fuel pump, that lead to the REM.
So that makes sense, and will make it easier to get to than crawling up underneath... (providing I
don't tear the paneling all to hell and incur the wrath of Mrs. Tanker!)

Damn, I was afraid that it controlled the fuel pump.... As far as leads going into the REM from up front
(not talking about wires going out to lights, etc., is there just one lead, or several?

I'm wondering if I can unplug the wiring harness going into the REM (from the "front" for lack of a better
term) to see if that eliminates the drain?

I'm thinking (and please correct me if I'm wrong) that I can do this, and the light goes out, that'll tell
me that the drain is coming from either the REM, or one of the assemblies that it feeds. (Rear lights
and fuel pump/sender, as you stated above.)

Thoughts? (And MUCH thanks for your help!!!)

I don't see anything wrong with your logit ... as a test. Of course, you can expect the PCM to go crazy and send codes when you disconnect the REM ... but they will go away when you get hooked-up again and a relearning period expires.

The control of the vehicle is very distributed. The "main brain" is the instrument cluster, then the PCM, the key gizmo (for security)... followed by all the other modules. (The REM also controls the rear heat/ac ... I forgot this).

The REM and the FEM each get: a power feed, a ground feed, and a "twisted pair" for communication with the PCM and instrument panel. This saves a lot of copper wire between the front and the rear of the vehicle.

The REM controls the rear lights, heat/ac, etc. - do these assemblies have separate plugs
that connect into the REM, so that they can be individually replaced if faulty, or do they all
plug into a massive wiring harness that must be replaced if one of the wiring assemblies go bad?

(I'd THINK that each assembly could be isolated or replaced individually, but we are talking
about Detroit electrical engineers here.....)

Does anybody have a wiring diagram that shows what all plugs into the REM that they could
scan and e-mail me a copy? I would SO appreciate it..... [email protected]
Or post it someplace that I could download it.

Trying to find a good source of manuals around here is like trying to find a Slurpee in the Sahara!

My 2000 is having the same problem. I am pulling about 700mA when it is shut off. This started happening the day after the rear wiper motor stopped working. There was one thread I found with this same problem and the wiper motor was a cold draw trying to set itself in the park position. I changed the battery and disconnected the motor to see if this takes care of the problem.

The second thread was a TSB issued: http://www.cartrackers.com/Forums/li...star/1363.html

This may be what you are experiencing. It entails the PCM to be reprogramed $99.00 when I called the dealer to see if it was covered.

Any news for this tread? i have the same battery drain problem, any help will be apreciated.

Thanks.

Were the REM is located? on my winstar 2001

Well, now my 2000 SEL is killing the battery is left for a few days without driving. It will drain the battery completely! The lights won’t even come on dim. I did notice something though; every time I hook the charger up to it, there is a relay clicking under the hood. To me, this would indicate that the circuit is charged, even though the car is off. The book calls this relay # 303 “SSP1 Relay” on page 174 of the Owners Guide. I could not find any information on this circuit in the Haynes. Does anyone know what this relay energizes?

I also have an ABS and a Brake Light problem on my 2001 windstar. All star one morning six months ago the brake light does not go off wen i unlocked the parking brake handle, i have to stop apply and unlook the parking brake and the light goes off it have to do almost a week then the light still always on.

One month latter the ABS light turns on, i check and clean all wheel sensors and wire connectors, check the brake liquid level, check the brake presure switch, check for leaks and nothing.
It could be the wire that goes to the parking brake switch?
what´s the correct voltage of the wire?
someone have a diagram indicating were that wire goes?

Thanks.

Sorry this message it was for another tread "ABS and Brake Problems" but i have both drain battery an ABS/brake lights problem too.

Checking the inside fuse box i feel the relay #1 and #4 are very hot w/key off, is this normal? the two front doors were open, removing fuse #16 (instruments group) produces clicking noise on these relays, i will close all doors and let one hour to see if the relays turns cold or stay hot.
Please need to know whats the voltage on the parking brake wire switch.

Thanks

do you have a blown third brake light buld

Found the problem, it was a bad rear wiper motor. It was stuck and not seating the wiper blade, so when the van was turned off it was tring to park the wiper thus draining the battery. Replaced the motor and have not had any further problems.
