No radio dome light flicker air bag light on

If the dome lights in your 2009 Cadillac CTS are not turning off, it can be a frustrating issue. Here are some steps to diagnose and potentially fix the problem:
1. **Manually Turn Off the Dome Lights:**
- In most vehicles, including the Cadillac CTS, there's typically a manual switch on or near the dome light itself. Ensure this switch is in the "Off" position.
2. **Check for Open Doors:**
- Make sure all doors, including the trunk and the hood, are completely closed. Sometimes, a door ajar can prevent the dome lights from turning off.
3. **Interior Light Dimmer Control:**
- Check the position of the interior light dimmer control, which is usually located on the headlight switch or dashboard. If it's turned all the way up, it may keep the dome lights on. Adjust it to the lowest setting.
4. **Ignition Switch:**
- Ensure the ignition switch is in the "Off" position. Sometimes, if the ignition switch is left in the "Accessory" position, the dome lights may stay on.
5. **Faulty Door Switches:**
- Each door usually has a door switch that signals the lights to turn on when a door is opened and off when it's closed. One of these switches may be malfunctioning. You can try manually pressing and releasing each door switch to see if the lights respond.
6. **Battery Disconnect and Reconnect:**
- If the above steps don't work, you can disconnect the vehicle's battery for a few minutes and then reconnect it. This can sometimes reset the electrical system and resolve the issue.
7. **Consult the Owner's Manual:**
- Refer to your Cadillac CTS owner's manual for specific information about the dome light controls and troubleshooting tips.
8. **Professional Diagnosis:**
- If the issue persists, it may be related to a more complex electrical problem. In this case, it's advisable to consult a professional mechanic or an auto-electrician to diagnose and repair the problem.
It's important to be patient and methodical when troubleshooting this issue, as it can have various causes. If you're not comfortable working on the electrical system of your vehicle, seeking professional help is a wise choice to avoid further complications.

Hello! Check fuse #11 (15A)...Are your Mirrors and Wipers working? If that fuse is good and mirrors/wipers with dome, door locks and radio are not working it looks very much like a defective Ignition switch...send a comment...

Most likely sense it was installed by factory, and all these issues came up at once, they probably did the fast easy way, meaning they most likely have them all on same circuit. Some wire short, most likely my guess is the power mirrors, is where I would start with looking for issue. However, what should take car of this first is look in fuse panel, you SHOULD have separate fuse for power mirrors and radio, as well as dome lights, but it is possible, they put them all on same fuse.

It could be your fuse. Check that first. If not, you probably have a electrical issue.

Ford's are notorious for electrical 'ghosts'.
If the fuses are all fine.. and the motors for the windows and the light bulb for the dome light are good... probably not much that can be done unless you want to give it to the dealer for diagnosis and repair, but they'll probably tell you they can't find the problem.

Saw this in many Buicks while working valet 7+ years, has to be some kind of recall. I suggest calling a dealer
