The gauge will get to just about 1/2 and then drop back real quickly to 1/4.
I will try the fan.
If that is it, where is the fan switch located?
I appreciate all of the help!!

Excellent!

Now the fan....is it always on when the Jeep is running? If so, bad sensor somewhere that's not turning it off.
