Replacing the headlight
bulbs on this 2008 Chevy
Trailblazer was quite a job.
To replace the high and
headlamp bulbs, the grille has to be removed
so the head light assembly can be removed.
The red arrows show all
the snap clips that need to be released on the
back of the grille.
I did this along the top of the
grille first, then I leaned the grille out and released the rest
of the clips.
Then the grille was completely removed.
Before I could remove the headlight assembly,
there was another electrical connector down
below, and also a bulb to remove.
The red arrow
points to the side marker lamp bulb socket. This
bulb can be removed by twisting it.
Caution: The metal prongs in the socket can bend easily,
resulting in problems re-connecting the wires.
Then I lifted up on the tab of the
wire connector (red arrow) and pulled it out.
The turn signal bulb is #3157 Amber.
I replaced the low beam bulb
with a number 9006 replacement bulb.
After changing the bulbs, I had to put
this all back together.
