water temp gauge quit while driving Pulled single wire off rear sensor + grounded.Needle did not move.When connected again turn key on and needle moves a small amount.Turn key off + needle moves a small amount to left.Is gauge bad or just need to remove instrument panel + do the "Eraser Clean" 1988 YJ 4.2 with 130,000 miles.Gas gauge has not worked since got this vehicle 22 years ago.
