I have pulled my instrument cluster to change light bulbs and hopefully fix my clock. Unfortunately my clock is not one that I can open up to work on so I will either look for replacement or except it as is. I see some open gears in my speedometer with grease on them and want to know what kind of grease to use to refresh with. Also my dash light switch doesn't operate smoothly. Is there a special lubricate for electrical switches? Any help with this project would be greatly appreciated.
