Most likely it is coming in throgh the trunk seal. On a dry day wash your car and then open the trunk and see if the trunk seal is wet and there is a trail of water entering the trunk
you dont its just for show evidently
it should be in the trunk, you will see a hole in the rear trunk panel where the rest button is located.
usually in the trunk,some are in the passenger right side kick panel. some galants do not even have one.Ex. 1995 galant s does not have one.
With a metal hanger ..... pull trunk latch ....go through the trunk/armrest opening.... the rest is up to u...... note hanger will mess up weather strip and or paint
If the back of the rear seat can be removed, it may be possible to enter the trunk and open it. If not, then the lock will either have to be picked or drilled out.
Open your trunk and find the wires that go to the bulb over the license plate. Twist the base to remove the light.
You open the trunk and remove the plastic wingnut screw on the backside of the tail light and replace the bulb and put the nut back on...very easily done without tools...
in the trunk
if your talking about the gas-tank fill door-the release lever is located just above the trunk release lever (on most models with interior fill-door release). it is marked with a "gas pump with hose".
You can access the bulb for the license plate illuminator by popping the trunk and looking directly behind the plate holder on the trunk-lid itself. There should be a swist type quick release plug that holds the bulb in place. (similar to the third tail-light on models without the spoiler)
I just had to change mine yesterday 4/12/08 you have to open your trunk, look right under where the 3rd brake light is to find wire running to it, twist to pop it out. Hope this helps. B.C.
You need to access the trunk lever through the back seat that folds down. Be sure to grab a flashlight and a long tool, such as a flathead screwdriver. This is easiest if you have a thin person that can at least put head and torso into trunk (basically lying down through back seat into the trunk) Next, have someone outside the car, with the trunk key. The person in the trunk need to manuever the flathead screwdriver in the trunk latch as the person outside turns the trunk key. I found out if the trunk is slammed shut or closed with a bit o'force, it jams the latch to open the trunk. So, when closing the trunklid, a little bit of pressure is all that is needed, so to prevent having to climb through the cubby hole in the back seat. Thank Mitsubishi for being savvy for the back seat trunk access ... :)
