So, I decided that I would try to fix the temp guage this morning. I pulled it out of the dash, and took all of the grounding nuts that hold the gage on and sanded of any corrisive materal. I then proceeded to put it back togeather. On my first drive to day it did not work. on drives 2-5 it worked. On my last drive of the day it did not work. It seemed to work very well for most of the day today, but i wan't it to work all of the time. Is there any other contack that I can clean

Thanks and Happy Bricking.
