Electrical Problems 96 limited

[Bill P.]

I recently purchased a 96 Limited 4x4 w/ under 100k mi. (after I smashed up a 97 sr5 in a snowstorm). In the past month, my high wiper setting stopped working, my license plate lights quit, my dome lights don't come on when my passenger side doors are open, and my lumbar support for the driver seat is not working. Are these problems related? I do not seem to have any blown fuses.

Thanks,
Bill P.
