Bill,
Your discussion thread was moved by one of the forum moderators.
I live in Catonsville, and own a 1967 Sean DeVille. I am a do-it-yourselfer, so I hesitate to offer repair services to the public. However, I am willing to assist you if you need help diagnosing your problems (as are others on this forum). If you provide specifics about the problems you are having with your lights and wipers, you may get a solution on this forum. There is a Cadillac LaSalle Club affiliated chapter dedicated to 63/64 Cadillacs. That website may have information you can use.
Where in Columbia are you located? I left a message on your voice mail last night. I work in Rockville on Saturdays, and in Elkridge on Thursdays and Fridays, so it would not be out of my way to take a look at your car after work. My home phone is 410-869-8619.
