Having issues with my 2004 XJR running hot. Turns out the cooling fan never comes on, even when I turn on the AC. I disconnected the two plugs from the fan and the larger one has 12 Volts. I assume that runs from the 80 amp fuse. The smaller 2 pin, connector I assume is the control for it. Does anyone have the details on the wiring to confirm what signal should be present to turn on the fan and where does that signal come from? I believe I have located all the appropriate fuses to check. The adaptive cruise control module does not work and has been removed.

The 'electrical guide is available on the 'sticky'

If you were not aware the module is in the centre of the fan and

it's not easy to open to investigate a fault.

Try scanning for codes?

Sorry but that 's all I know.

 

Invest in a scanner. Mine for the Jag is fairly basic, but will read real time info for reference. https://www.stahlcar.nz/

 

Meirion1 I will check the wiring diagrams again. Just too many areas that are modules that cannot be investigated further.

Jason no codes on OBD, but see the link for the icarsoft Jaguar device for $315. I believe the shop I used to repair my Jaguar has one, unfortunately they are located 75 miles away and I am reluctant to drive that far without the cooling fan. functioning correctly. I may just need to purchase my own.
