I have replaced the FEM (front electronics module) and ignition switch today becauase the forums I have seen by searching google said those were the only things to cause the issue.

Basically what happens is I have to unhook the battery to turn off the radio, windows, wipers, headlights, tail lights, anything and everything electronic in the car. I have looked everywhere to get this fixed. Does anyone else have any ideas?

There should be an accessory timer relay that shuts all that off. The module should be getting a signal from the door switch. Do your interior lights work properly?

 

[krakkamike]

yes and no, they only work right when the ignition is set to run, not when the key is out or set to off.

Canuck623 has an excellent point on the relays - this generation of Windstar used "Low Side Switching".

NOTE: The rear light and interior light functions are controlled via the REM, not that I think that is the problem. I have a few ideas, but think, perhaps some more information may be helpful.

I recall TSB 02-13-9 Battery Drain, which I am attaching. Thinking out loud, I am wondering if it is a bad relay, bad ground, pinched wire.....

Krakkamike, have you checked the fuses and relays in both the Battery Junction Box and Central Junction Box?

Here is the Forums link on the subject.

Hope this helps.

I have started on checking relays but havent been able to find one that has cuased the problem yet. I plan on getting back to the garage later this evening though.

Thanks for the link and info! I will let you know when i finish the relays. I havent seen a blown fuse yet though.

Now that I think of it the problem started after an aftermarket radio was installed. A good wiring harness was used and no wires were cut. I will pull that radio out and check to see if there are any pinched wires tonight as well.

thanks again!
