The manual does not haveinstructions in replacing the headlight bulb
59Shadow.
Thank you for sharing the information on the light bulb. You just saved me money from having to take my 2003 Trailblazer in to have the low beam bulb replaced. I did exactly what you said.
1 Open hood and lock.
2. Take filter cover off (4 screws and they stay with the filter).
3. 3 inch cover pulls off.
4. Twist light bulb 1/8 turn.
5. Unclip the wiring harness to light bulb assembly.
6. Test by turning light switch on.
7. Align assembly with light housing and turn 1/8 until it snaps in.
8. Put 3 inch cover back on.
9. Place filter cover back on and hand tight the 4 screws.
10. Close hood.

2002 Chevrolet Trailblazer
Several days ago I was running around town and vehicle was running fine. About the third time UI startted it it was barely running. It appeared to me the choke had stuck.
I took it home and removed the air box and sprayed the throttle body down with a carb. cleanner startted it and it ran better than it had in a while.
Last night as I startted it to come home from a resturant it is missing and the "check engine soon" light flashes on aceleration. then goes off.
any ideas?
This morning my 2005 Chevy Trailblazer was driving fine and then it felt as if it was sputtering (I felt it through the gas pedal) or missing, so I accelerated and it kept going but then my check engine light flashed on and off several times and I slowed down a little bit, then the light went off. I made it to work but am afraid of what may happen come lunchtime. Any ideas?
It sounds like u got a coil pack going out. Alot of times when your engine is cold or when you arn't putting a load on it the coils won't fail. How ever when the engine reaches operating temperatures and there is load on the coils that is when they are going to break down. my advice would be to get a scanner and see what cylinder the missfire is at then swwap that coil to another cylinder to verify that the coil is defective. If it is purchase another with a new spark plug put it in and let it rip.

Check engine light on, diagnostic code 0128 and 0410 keep coming up
P0128 - Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)
P0410 - Secondary Air Injection System Malfunction
(has to do with exhaust system)
Note: There is a technical service bulletin (TSB) regarding code P0410 for a
number of GM models. The TSB calls for the replacement of the AIR pump and the
installation of a new secondary injection hose.

I do not see the fuse labeled for this air pump in either of the fuse boxes located under the hood or the second row seat. Ther is a 15amp fuse for the air pump solenoid, but no air pump.
my 2008 Trailblazer has the same issue P0411, changed the Air check valve and still the light comes on
