Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Is this the coolant or engine temp gauge that quit working?
Let me know so we can continue,thanks Pete
Did the engine coolant temp sensor you replaced have a dark green single wire on it at all?
O.k.,the engine coolant temp sensor for the gauge on the instrument cluster has a green wire attached to it.Here is a diagram on this here.Part number from GM for this sensor is 15326386.
This sensor is either located on the side of the drivers side or passenger side cylinder head near the exhaust manifold or is located on the intake manifold.You will want to locate this specific sensor and replace it and see if this resolves the issue.Inspect this green wire for any damage needing repaired or replaced.If the sensor is replaced and wiring is all o.k. then the fault is in the instrument cluster itself with the instrument cluster needing replaced to correct this issue here.
