And I would almost guarantee it's the front one. Water gets in those
housings very easily and fries the bulbs, especially if you drive
through standing water of any depth. And it's not a user replaceable
Most certainly is user replaceable and you can stand while doing the switch
by removing the hood stop. Also can be done from the bottom by removing the
panel in front of the wheel well to get to it but in that case it's nice to
have it off the ground, but not necessary. You might want to do it that way
and pull the entire assembly and see why it gets water in it, I've driven is
some mighty hard rain storms for hours without getting water in them.
Never lost a bulb in a C5 but I have in the C6, I've changed them for club
members because I got all of the bulbs, about 300 of them, when my B-I-L
closed his parts store. I replaced the entire front end on my '98 from a
deer hit and there is no reason for that unit to leak by the way it's made.
Didn't mean to imply that you didn't, only pointing out that there is a
reason, they may have a bad seal or have been cracked. Either way it's not
normal, they are sealed units to a point, they have to breath.
The '04 spent 2 days in Portland Or. in some rain the like I've seldom seen
and the '98 was in Cincinnati in such a down pour that it was hydra planning
without a loss of any bulbs. I drive them year round in some bad weather
that sometimes catches me and I've never seen water in this style light that
wasn't there because of a bad weld of seal. Not even the deer hit broke the
seal. On the other hand I've seen light units that have water sloshing
around in them when they lose a vent check or are cracked, Chrysler in that
I finally got some time to replace the bulb. the easiest way is the
- turn on the headlights and go back one to parking brakes
- take off the bezel/casing around the headline
- pop up the hood
- you could access the bulb under the headlight lamp
don't need to go underneath, easier that way
