2003 mitsubishi galant. need to change mom's brake light (left). how do i get to it? got to place where (looks like) fuses are - now what?

SOURCE: service engine light on 2002 mitsubishi galant

it could be the spark plugs, at least that is what it was for mine, if you have over 50k miles without a spark plug change i highly suggest one, also a oil /transmission change would be great for your car too if you haven't done those reciently. I would also suggest using a higher grade gas, sometimes this fixes the trick too.
If you try all those and still experiencing hard transitions please let me know and i'll try a more indepth analysis on your car.
Thanks jyotsna.

if it has a trailer package look at the splitter when you take off the tail light cover might be that plug.

SOURCE: My dashboard lights don't work on my 2003 mitsubishi galant. Is there a fuse box?

Yes, There is a fuse box ... your owners manual will asssit you in locating it and the suspect fuse ... do your parking lamps work? Is your dimmer turned all the way down?

SOURCE: 2003 MITSUBISHI GALANT HOW TO REPLACE HEADLIGHT BULB

First you disconnect the 3 prong electric plug. To disconnect squeeze the side tabs together (hard) and pull away from the bulb, then you can pull off the protective rubber covering, (its a little snug so give it a tug from the 2 tabs on the top and bottom).

Next unscrew the little Phillips head screw to loosen the bracket that clips in the bulb (take note of how the clip is installed before you remove it, it holds the bulb securely in place).
Just loosen the screw as you do not need to remove it all the way. Pull out the old bulb and replace it with the new one.

The bulb has 3 spacing tabs on it so it can only go in one way. Make note of this when you remove it so you may replace it the same way. follow the steps in reverse and your done.
Note: The little wire clip that holds the bulb in can be a pain. Make sure you get a really good look at it, since it pops out as soon as you loosen the screw. If you get lost, you can always look at the other headlight. Oh, and don't do this in the dark.
