What other trouble shooting can I do......or is it the ECM?
2001 XJ 2 WD
Electric fan runs constantly due to previous owner wiring in a relay by the fuse box.
When this relay is disconnected the electric fan stops.
With the extra relay disconnected - disconnect the coolant sensor connector the electric fan will come on.
The relay in the PDC has been replaced. The fuse in the PDC has been checked and is good.
I am thinking it might be the ECM but do not want to replace that unless I am sure.
I just do not know what else to replace.
The temp sensor on the back of the engine ha no bearing, right?
