Dash lights not working, dome light stays on, etc.

Alrighty then...I'm having several electronic issues and I have a question (several actually...but we'll keep it short-ish).

Problems:
- My dash lights aren't working...to be clearer...the red pointers work and the warning lights in lower left area are fine...it's really the white (and any other) backlighting that doesn't seem to be working.
- Add to this...the dome light doesn't automatically turn off in either mode
- the window switches stay lit after the car is off (beyond the 5 mins)
- the passenger side A pillar switch/button is pushed into the frame and I'm not sure it was working anyway

Troubleshooting steps so far:
-I've tested the window operations based on several members recommendations and all seems to be fine there.
- The door locks properly manually and with the remote. But the interior door lock levers don't seem to be doing anything. What's supposed to happen when you pull up on them?
- A-pillar button: Once I dug it out of the frame, I pushed the button in for 2 mins to see if that would effect the dome light (or anything else) and it didn't seem to do anything. I am getting a new clip to reinstall it in the frame and test if that makes any difference.
- I am keeping the car on my Battery Tender so the battery stays fresh

Questions:
1. Could these issues be tied to one common problem?
2. Any suggestions on how to troubleshoot any or all of these issues?

Many thanks to those who have helped so far, but I wanted to consolidate in one thread with all of the issues. Thanks in advance!

 

Thank you. That's the switch in the trunk, rt? Where do I find the ecu?

 

I've adjusted it up to full strength at 20. No change.

Dome light stays on unless I manually turn it off.

 

Battery is brand new. During the mechanical PPI, it was determined the existing battery was very weak, so I had the dealer install a new battery. After purchasing the car, I had a detailer do some work on it and the new battery died on him. So, I think something was up already. Plus, I've been keeping her on a trickle charger so the battery shouldn't be an issue.

 

No...detailer put it on a charger and waited until battery was charged before starting (actually, it wouldn't start until it was off the jack stands and back on the ground). No jump start done.

 

Thank you. I'll do that with my multimeter. I have that ring part being sent to me from the guy who did my PPI (who's also thoroughly perplexed since he said he checked all of this stuff).

 

Good idea! Ghetto, but still good. Haha

 

Thank you, Dan. I can't see the file on my phone, but will check on my computer soon. Here's a pic of the dash as requested...

 

Was just forced to do this! Funny enough, i used a part of a Ferrari box.

where did you get the clip? I assume you're talking about the black circular part that holds in the switch? i have the rubber part and the new switch, but missing the critical piece.

Plus, the new a pillar switch didn't change anything...window switches still alight permanently (and ran down the battery in only 3 days...argh!)...so looks like it's going to have to go to an expert.

 

Thank you! That's the part I need.
