Re: 2005 CV power lumbar switch. .
To be honest, you can attach a screw and a zip tie, depending on how the clips are broken. They are really thin and flimsy.
If you want functional, you will have to go to the dealer. I probably have a black lumbar switch bezel, but it too is also cracked. So is the grey one in my car, that I have affixed with zip ties under the seat that you cannot seat at all.
