The first Jeep JK Wranglers came with mirrors that had a way of collecting water from rain or being washed and trapping it inside up against your doors - not a good thing. Later JK's saw improvements to the mirrors which included a small notch at the bottom of the flange and, while it did help water to drain out, it was still a bit too small and had a tendency to get clogged up with dirt and debris. To fix this, a bigger drain hole is needed and this easy to do mod will help you to make one.
What You Will Need
• Hand Drill
• Small Drill Bit
• Center Punch
• Torx T-40 Bit
• Ratchet
Instructions
1. Roll down your front windows.
2. Use a center punch to locate the point where you will need to drill a drain hole on your mirror's flange.
3. Open up your front door and use a Torx T-40 bit to remove the 2 bolts securing your mirror in place.
4. Carefully remove your mirror from the door (notice the dirty water that was trapped inside of mine). If you have power mirrors, just pull it out far enough to work on, there is no need to disconnect it.
5. Clean out the backside of the mirror's flange and then carefully drill a hole through it at the point where you marked it off earlier with a center punch.
6. Clean out the hole of any loose plastic.
7. Reinstall your mirror and secure it in place with the 2 factory bolts. A Torx T-40 bit will be needed for this job.
That's all there is to it. You now have mirrors that should drain a lot better. Here are a couple of shots of what they should look like when all is said and done.
