There seems to be a common failure part for a speedometer and odometer that fails. It works sometimes and then other times it doesnt work. I do not know what the part is or its location on my 95 Sahara Wrangler. I have searched and searched and lost the info that I found that included the name of the part that I believe I seek. Can you guys help me out with the name and location. I am new to this site and have not figured out where to find the list of common ailments and such. Thank you.
