There is a square black box on the RH side of the engine compartment with the emisson label on it. Four phillps head screws holding it down, remove the screws and lift the box off, the filter is straight forward replacement after that.

Trailblazer loses power. changed the o2 sensors, secondary air injection pump check valve,transmission oil an filter,an fuel filter. what other thing can be wrong

Hmm, I thought the fuel filter on 05' was on the pump in the gas tank. Must of started that in 06', mine is in the tank which sucks, my older 02' is external. Have you cleaned your throttle body? If not, likely this is your problem. We don't have a pcv system so our throttle bodies collect lots of carbon and gunk. Remember to unhook the batter while you remove the tb. 4 bolts, and you can reuse your hard gasket many times over. I like using Seafoam spray and rag to clean as it's sensor safe.

How do i change the headlight bulb on my 05 uplander

On my 2003 trailblazer (as far as I know they are the same), See note below for passenger side. Remove the dust cover on the back of the head light assembly (black round rubber cover about 3" in diameter, just pull it off), disconnect the plug on the bulb, turn the bulb a 1/8 turn and pull it out. Then reverse the process for assembly. ***NOTE***If you are trying to replace one of the bulbs on the passenger side, remove the air filter housing cover and displace the filter for access to the dust covers on the back of the head light. 2 screws hold the air filter housing cover on, one directly behind it and one on the side (drivers side of air filter housing).

How do I change the air filter on a 2004 Chevrolet Trailblazer?

The air filter is in the right (passenger) front corner of the engine compartment. Use a screw driver to remove the four screws securing the cover and the air filter comes out. Be careful not to drop the screws as it's easy to do and you'll likely never find it again. Good luck.
