I have no movement at all on my temperature gauge and the engine cooling fan has never worked. Am I looking at two seperate faults here? Or is this more likely to be the temperature sensors. I say "sensors" as I have a repair manual and im confused as it states coolant temperature sensor and temperature sender. Are these the same or different locations also I have checked the fuse for the engine cooling fan and is ok. (30amp)

Hello,

On this vehicle the radiator cooling fan is controlled by Constant Control Relay Module (CCRM). A faulty CCRM will not allow the fan to come on.
The module is located under the hood on the right hand side (if you are facing the engine), I have attached diagrams for your reference.

The temperature sensor can be connected to the fan issue but check the CCRM first as it is a fairly common issue.

I have attached the diagrams including the wiring schematics for your reference.

Please let me know of any questions.
Thank you.
