I understand your frustration with the overhead DVD player in your 2015 GMC Yukon. Let’s break down how to both fix the existing unit and safely remove it if needed.
Step 1: Diagnosing the Problem
Loose Mounting
The looseness of the DVD player could indeed be causing intermittent power issues due to a poor connection. Here’s how you can tighten it:
1.
Inspect the Mounting Screws: Carefully remove the plastic cover or bezel around the DVD player. This usually just snaps off, but use a plastic trim tool to avoid damaging it.
2.
Tighten Screws: Check the screws that hold the unit to the ceiling. Tighten them if they’re loose. Ensure the unit is securely fastened to prevent movement.
Electrical Connection Issues
Given the symptoms (power light changing colors but not staying on), it sounds like there might be a wiring or power issue:
1.
Check Wiring Connections: With the unit removed from the ceiling, inspect all wiring connections. Look for any loose or frayed wires. The power issue might be due to a poor ground connection or a loose power wire.
2.
Wiring Harness: Ensure the wiring harness is securely connected. Sometimes the connectors can come loose over time.
Step 2: Removing the DVD Player
If you decide to remove the DVD player, follow these steps to do it safely:
1.
Disconnect the Battery: To avoid any electrical issues, disconnect the negative terminal of the car battery.
2.
Remove Plastic Trim: Use a plastic trim removal tool to carefully pry off the plastic trim around the DVD player.
3.
Unscrew the Unit: Locate the screws holding the DVD player in place. These are usually Phillips-head screws. Remove them carefully.
4.
Disconnect Wires: Once the unit is loose, gently pull it down to access the wiring. Disconnect the power, ground, and any other wires connected to the DVD player. Note or label each wire for easy reinstallation.

Replacing the DVD Player
If you decide to replace the unit, here's how to install a new one:
Mounting: Follow the manufacturer’s instructions for mounting the new unit. Typically, this involves securing it with screws in the same location as the old one.
Wiring: Connect the power, ground, and any other necessary wires according to the new unit’s instructions. Since the wiring is already run, this should be straightforward.
Testing: Before securing everything, reconnect the battery and test the new DVD player to ensure it functions correctly.
Final Installation: Once confirmed working, secure the unit fully and replace any trim pieces.
Additional Tips:
Reference Manual: If possible, refer to the user manual of the DVD player for specific instructions or troubleshooting tips.
