I need to replace the multifunction switch in my 02 ls8. The dealer says that it is the reason behind my non-functional auto wipers. Has anyone done this?? What do I need for the prodject besides the normal tool kit? Thanks. Also...and I know the airbag light thing has been beat to death... I have a code 15 what ever that is. I have already had and fixed (numerous times) the drivers seat connector. Code 15 has not been associated with the clockspring on the posts that I have searched. Anyway any info would be apreciated.
