lucerne 2008

Hello from Arizona with a 2008 v6 Lucerne cxl, I am having an issue with my abs and traction control. I had this issue a couple of months ago, I replaced one of my tps sensors and it went away and is now back. It only ever comes up when I drive up hill very rarely my abs will come on when I am...

I have a Lucerne with the 4.6 32v Northstar and i know that in some buick models they put a supercharger on the northstar does anyone know if this is possible on the Lucerne? Im looking for some more power other than the tunes and cams and all that. I guess around 350hp isn’t enough for me.😂

I would appreciate any advice on how to access the HVAC center vents in a 2008 Lucerne. An item fell into the center vent and into the abyss. Many thanks.
