If your jacks look like the ones Below then you're already aware there is not much you can do to replace or repair them. Atwood sold to another company & the new company had no interest in keeping the Atwood jack line going. Unfortunately, We have 2 of these switched & 2 Non-Switched Jacks that, originally, was installed on our 1994 Lance 990. However, I'm going to try & do what I can here with these jacks & give some direction on what you can do if all else fails.
