All fuses in Centeral Junction Box [CJB] = ok Ohm meter to fuse test pins
Swapped & Tested Accessory Delay Relay [ADR] with Blower Motor Relay = ok

All other components appear to be functioning properly.

Other posts mention a cause of inoperative windows caused by a wire short in the harness of driver’s door to body.
Can this short affect the Sunroof, Interior Lights, Antenna & Outside Mirrors?
I’ve read many posts regarding the inoperative windows. I’m hoping I don’t have to pull the driver’s door harness apart to find a short.

If it's the driver’s door harness, what wires should be tested?

I have Manual for 200-1 Taurus/Sable.
Is wiring same for 200-0, same as 200-1?
I have a 2000 Sable Wagon

Pic of driver's door to body broken wires. I am 3 for 3 on G-4 sables. Various things fail. And on the wagon, one of two broke wires in the accordion to the hatch. That one killed the radio as it shorted to the backup lights wire.

Just a sharin of experience.

Hi Chart
Thanks for the reply.
I viewed the posts regarding the "infamous" driver's door harness [ddh]. Obviously, I was praying not to have to open it up. What are the particular wires in it that are most likely to fail?

I'm curious about the antenna wiring because I didn't see any reference to it being connected to the Battery Saver Relay nor Accessory Delay Relay. Are there wires in the [ddh] that connect to these? Or can I have multiple shorts?

In addition, I couldn't find related wiring to neither the Power Antenna nor the Power Outside Mirrors to the Battery Saver Relay nor Accessory Delay Relay. Are there wires in the [ddh] that connect to these? Or can I have multiple shorts or bad grounds?

NOTE I've had Merkurs that are notorious for bad grounds. Is the [ddh] the achilles heel of the 4th Gen?

I would start with fuse #26 under the dash = 10 A. Mirrors, Power antenna, Deck lid lamp, and such, interior lamps. But I am using the '01 book for my fuse number here. Yours might be different.

All fuses checked ok.
cd player is ok, stereo obviously has poor reception with antenna in down position.
I'll check rear lights.

After opening the driver's door harness and fortunately not finding any bad wires, I decided to R&R fuse 26. Just because the fuse [#26] looks ok and has continuity, doesn't mean it's ok. For now all items are working, but the question remains... why did fuse 26 blow? Was it a bad fuse or is something causing a short?

As a note to those who do not have the electrical diagrams. Fuse 26 Feeds the outside mirrors, antenna and "Battery Saver Relay" This relay feeds the windows, interior lights and sunroof.

How did the fuse blow? Was it visibly open in the middle of the element or did it look OK in the center and still be open.
Shorts will blow the fuse in the center, old age fails (as I call them) will open at the ends of the element and happen over time. Poor connections at the fuse ends can transfer heat into the fuse and cause that kind of failure also.

John aka repairman,

Initially, fuse had very minimal carbon at center, but now has a break at center of "U". Not at ends. You have to use a magnifying glass to see the break. Some carbon build up on prong edges, but nothing more than I've seen in many old fuses in many other cars.

I still have inoperative LR window. Previously, I jumped pwr & gnd to motor = ok, R&Red window switch and "massaged" the window to make it function before this recent occurrence. I'll have to test window switches and motor again. Hopefully, just a sticky mechanism.
