No dome/map light, rear wiper, key chime or key illumination, everything as far as I know. Checked the rear wiper fuse and under hood dome light fuse. Rear wiper and washer on same fuse and the rear washer work. Any ideas?

Did this all happen at one time? Can you check for power at the rear wiper fuse? Does the engine start and run? The items you have mentioned are not on the same circuit. The rear wiper fuse is powered by the ignition switch. I would turn the key on and test all fuses for power, here is a guide to help you:

It seems like many more electrical accessories would not be working if the ignition switch was bad FYI, check out the images (below). Please let us know what happens.

I had the ignition switch replaced; it was stalling the car. The car runs like a top. These problem are happening all at once. I got a new rear wiper motor then I checked and have no power but power on the washer pump.

I'm not a mechanic but sending me on a wild goose chase to check unrelated fuses seems unproductive. Sounds like it could be canbus related. I have seen old threads for this issue but they were so old not resolution. No old known issues?

Here is the rear wiper wiring diagram so you can see how the system works. I don't see a CAN BUS? That's why I ask if it all happened at once? Sorry for the confusion.

I'm even more confused. Yes, it all happened at once. Should I still check all the fuses? And if there all good?

Yes, check the fuses and more importantly see if the fuses have power. There must be a main feed that is not working. Start with the fuse for the rear wiper then I can trace it back.

Okay, a fuse was blown in under the hood box, everything working except dome light will not turn on when I open the driver's door with key or physically open it, dome light turns on all other doors open. Swapped switches and still no light at driver's door. Newer switch on driver's door works on other doors.

I think it was the LED bulb that blew the fuse. The LED was dead and open when tested.

So, did the rear wiper fuse have power on both sides?

I never got that far. I purchased some 7.5 fuses to change out the corroded looking one under the hood. I could check then. Do I need to see if I have power at the wiper to fix the dome light not coming on with driver's door?

If you check for power at that fuse, I can see if the power feed affects the other circuits.

My mistake. The driver's door does turn on the light (very dimly) I thought it was ghosting because it's LED but that is not the case. I got some 7.5-amp fuses coming (I used a 10) I'll check more later.

I have power on both sides of the rear wiper fuse. In the dark the drivers door opening or key in door lock do not turn on the dome light. The dome light is/was(LED) ghosting, when I do the aforementioned it gets dimmer. I thought it was working dimly but I was wrong. All other doors turn on the dome light. The dome lights were not ghosting before this. And the back dome light work properly, no ghosting.

So, the rear wiper is getting power but still does not work, correct? I am starting to think this is a ground problem, has the wiring been tampered with?

Changing the light fuse (7.5) under hood fuse box made everything work except the dome light works normal with all doors except diver's door. The dome light switch seems normal, on off auto - except the bulb ghost when in auto mode. I messed with the brand new D.D. Switch and clean connection.
