my sony stereo goes continuing 12v and other wire is 12v when acc/ignition is on.
that i´m using to relay trigger. i don´t remember the colour but stereos are working fine a long time.
OK, that's what I needed to know.
I believe your problem with the interior lights is not at all related to the brown wire mod. I believe it's just coincidence or chance that the dome light problem is happening right after doing the brown wire mod. The two problems are, most likely, unrelated.
sorry if i don´t understand something. i have to translate many words with dictionary
I don't know what your native language is, but I'm quite sure your English is much better than my ability to write in your language.
edit: i don´t understand how interior lights are connected with 4wd.
they are using same fuse that is only thing i noticed.
interior ligts are off when i take fuse number 25 or 27 off
As I already mentioned, I don't think they are related. Can you use a test light or multimeter to measure for power at certain points? Here's how I would approach the problem.
First, I have to ask a dumb question: Is the dimmer adjustment knob turned all the way up past the 'click' to the 'ON' position? What happens if you turn the dimmer knob all the way up and down? With the parking lamps on, do the instrument panel lights dim properly?
Second, I need to know EXACTLY which lights are on. Please confirm this for me:
The rear dome lamp/cargo lamp
right hand front door courtesy lamp
left hand front door courtesy lamp
dome lamp
Are there any others?
There are three possible problems that come to mind: First, there could be a door latch that is telling the GEM that the door is open. This problem would also show the 'DOOR AJAR' warning on the instrument panel. If you're not getting the DOOR AJAR message, we know that can't be the problem.
The second could be a stuck relay. The relay that controls the dome lights when the GEM tells it to is in Auxiliary Relay Box #4, which is located on the driver's side rear quarter panel, just below the window. It may be possible to access the relays from the jack storage area, but it'll most likely require you to remove the trim panel to get to them. If you remove the relay and the lights go off, you know you have either a bad relay, or the GEM is calling for the lights. We can troubleshoot this further if that turns out to be the case.
The third possibility that comes to mind is a bad dimmer control module. When you turn the dimmer all the way up past the click, it closes a switch that activates the dome lights, bypassing the relay completely. Unfortunately this may mean tearing the dashboard apart to access the switch and replace it... not an easy job. It may be possible to access it by removing the three screws that hold the fuse panel in the dash, pushing it out of the way, and reaching up inside the dash, but you would be working blind, and that's never an easy thing to do. But, if you can just unplug the dimmer module and the lights go out, then you know that's the source of the problem.
Let me know if that makes sense, or if I can be any more help. Good luck!!
