Thank you all for replying to my message. I did notice today that both the main and the trip odometer are trying to roll over again. I'm not fully sure what to make of this, though I am starting to think that whatever is powering both of these, is slowly going out.
I read the web site that I was given a link for. The web site was very interesting, and it looks like something I can handle. I'm curious if anyone might know how much these parts could cost to replace? Thanks again!
