Re: 1996 Deville Troubleshoot update
As Sub said, check the Tech Tips section. I think there is a tutorial on how to clean it. If it is a '96 and has never been done, you'll be surprised at how filthy it is and will take some scrubbing. Doing it once a year will make it much easier. I do mine every spring.
