So my water temp. on the dash isnít really working. Sometimes it wonít work at all and other times it indicates the car being cold, like the needle will just hit the edge of the blue. This started awhile ago and be kind of rare for it to act up, but now its more frequent and will rarely work correctly.

My idea is its an electrical connection. But where do I look first? At the dash behind the gauge? At the water temp sensor connection?

Or is it the sensor itself?

Any input would be greatly Appreciated!
