Question Power locks dont work radio and clock screens blank

We are having a bunch of electrical issues with my wife's 2008MDX (no NAV), they all appeared in one day after she came back from a CO state inspection station:

1. Central door locking is not working from neither key fobs nor electric lock buttons on any door. Basically key fobs do not do anything, but the LED come on when I press any of the buttons.
The car can not be locked/unlocked unless I use manual lock switch on each door.

2. Seat/mirrors/steering column positions are all erased from memory and do not get restored by any action (fob or pressing mem1/2 buttons) even after setting new positions.

3. Radio and CD work, but they do not display anything on the radio screen.
However, if I turn on A/C then the radio screen shows all the regular climate control info such as temp/mode etc, so the radio display is not dead.

4. Clock display is blank, I can only see backlighting on it.


The battery is brand new and charged to 100% 12.9V

I found this very informative thread and will try to follow it, I just wish I had manual handy (I know I bought it but can't find it now . Unfortunately it only partially covers my car's symptoms.

Maybe unhook the battery for 5 minutes or so and see if that does anything. A "re-boot", if you will.

After studying power locking system electrical diagrams and replacing fuse 7 all is fixed and order is restored.
Seems like one very important fuse, or Acura did not study how to componentize (spelling?) systems.

That also fixed the rear gate and a fuel cap, which could not have been opened by hand.

Fuse 7 is it from the engine compartment, do you have a screen shoot of the fuse location by any chance.
Thanks.

I replaced fuse #7 in the driver's foot well location, no pix.
