Rear defrost locking My doors???
Ok- So I did a search and didn't see anyhting for this one.
I got in my 1998 Disco this morning, hit the rear defrost window button (top left side button of steering wheel dash) and my doors locked. button lit up and all doors locked.
None of the other buttons on that side (rear fog, volume +/-) or any side did this, only the rear window defrost button.
I'm gathering something is shorting out some where....???
Any thoughts out there or any one else have this one happen to them?
----1998 Disco I LE just passed a full inspection today here in PA with flying colors.

The wiring diagram in the RAVE shows that trucks with alarm system share the MFU (multi function unit) for some related functions (timer) with the rear defrost system, which also uses it. There's always fuses, water on connectors from sun roof leaks, and ground points that have come loose and forced electrical current to find other ways to the battery. The ETM (electrical troubleshooting manual) and a test light will be helpful.

Hello anyone home, I just said I had this issue!! Check your fuses for the mfu, it controls a bunch of stuff, door locks, dome lights, alarm, defroster, rear wiper, the owners manual specifically states when dealing with electrical issues the check the fuse associated with the problem and the mfu fuses, 12&13 I think.
