I have a 1995 jeep cherokee sport and the thermostat gauge isnt working im not sure why. it just stays at 0 and never moves but the jeep runs just fine. somebody please help!!

 

There is a temp sending unit ontop of the head on ds near the back.When that goes bad the temp guage stops.They are like $15 at parts store.Be careful when replacing it.Its hollow brass and will break fairly easy.

 

Thanks!! ill be sure to replace that

 

No problem at all.Thats the last bit of help I give thanks to a certain moderator.See Ya!

 

I replaced mine recently for the same reason BUT I got the part from Autozone and it reads exactly 1/4 of the gauge higher than it should (normal operating temp shows just below the red)
Also, make sure the sensor has continuity and changes resistance when you breathe hot air on it. The first couple sensors they gave me were wrong/bad. They had a slightly different single connector pin and did not read were open between the pin and case. I have to find someone else with a good one and replace it. even though I know its not overheating, I still find myself starring at the gauge a lot.

 

Well dont know the story but i will miss your input. happy trails!
