Welcome. High or low beam, left or right?
Customer: replied 6 years ago.
right low beam
Expert:  GM Tech (Cam) replied 6 years ago.

Ok, there is enough room to do this if you only take the air filter housing out and the rubber flap. Remove the clamp and pull up on the housing to remove. Use a screw driver to remove the push pins and remove the rubber flap. Then you can twist and remove the bulb.

so it will be a different procedure if I have to change left low beam, since I plan to upgrade the left one too to a brighter and upgraded bulb
Expert:  GM Tech (Cam) replied 6 years ago.

Yes, because the actual procedure requires the removal, the right side is a short cut.
