Sorry Russ but can't wait a couple of days. My wife says I have no patience but I tell her I have a lot cause I never use any. Got the wiper knob off with the use of some vice grips, only way my old hands could hold it. Didn't mar it much. For the light switch it took a little research and found some info on the a body site that mentions a button release and sure enough I found it and the knob pulls out easily.
