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).
the air pump on 2005 trailblazer is located on the frame rail on the drivers side .by the drivers door
Are you looking for the cabin air filter or the engine air filter?
Remove the air filter housing cover. The air filter will lift out. Drop the new air filter into the housing and replace the cover.
