91 Mustang LX Hatchback 2.3L

Starting last week the power windows, wipers & radio keep working even with key off and removed. Cigarette lighter & power mirrors also work with ignition off but I THINK they've always done so. AC blower motor works as it should with igniton in RUN position.

What I've done: I've replaced the ingition switch & cylinder lockset. Also removed under dash fuse panel and looked in back to see if anything looks amiss and because the radio has not worked properly for a long time I removed it from the vehicle in case it could be shorting something.

IMPORTANT??? How this could be connected I don't know but I'll include it because this is when it started. The map light, not the dome light, but the aimable, flashlight looking light fell from the headliner when my daughter was returning from school and the radio quit working. We checked and replaced a blown fuse and radio started back working BUT would not turn off with key swithed off. We then noticed the other things also did not turn off.

 

Also let me add this. I didn't just arbitrarily replace ignition switch and lockset just to see if this was the problem. My daughter has been having to "wiggle and position" the key in the run position to get the A/C blower to work and key would also remove with igintion in the run position. I really thought when I replaced these it would cure my present problem but no such luck.
Thanks,

 

I would have suggested checking the ignition switch too, the only other thing that comes to mind is that perhaps the map light circuit had been getting intermittently shorted out prior to falling off and maybe fused itself to some wires for the affected circuits. I'd take a look at the back of the fuse block, in either event you'll need to check for power to the affected circuits starting at the fuses and working your way back, a wiring diagram would be very helpful as you could look for a common splice or connection on the circuits.

 

I spent most of the day Sunday but finally got it. There was a large pink wire that provided power to the power window circuit breaker in back of the fuse panel. If I pulled breaker the power windows would still work with the key out but the wipers and radio would not so I figured the problem should be this wire. It was then I noticed the passenger window did not work at all regardless of switch. All this time and I'd only been trying the driver side window. I pulled the kick panel on that side and the pink wire was part of a two wire connector that serviced the pwr window. When I unplugged this harness drivers window, radio and wipers worked normally. Some of the junk I have left over from rebuilding this car was couple of doors so removed switch panel from that and now working great.
Thanks,
