Have 2002 S-Type 3.0 with 65K miles. Finally getting around to work on the radiator fan issues. Haven't had the fan go on in ages - doesn't turn on when I turn the a/c on high and fan on nor does it come on when the engine is running hot (previous post https://www.jaguarforums.com/forum/s...ng-hot-100086/).


I went ahead and got a replacement fan, shroud, controller and replaced the existing fan. Still fan will not turn on.


I also checked the fuses - the 80A and the 10A fuses in engine compartment are fine (as are the other fuses) - confirmed continuity with multimeter.


Didn't check any relays. The harnesses looks good on the outside, no frayed wires or obvious breaks - haven't checked continuity with meter yet.


I am assuming that since both the A/C (which runs fine otherwise) and the hot engine do not turn the fan on, it must be something that is common to both?


For now I would like to assume that replacement fan, controller are in working order and focus on other areas first.


Any suggestion exactly what/where I should be looking at to narrow down whats broken?


Any help would be appreciated.
(BTW did search for similar issues - people had wires that were frayed or not connected or suggestions to check fuse).

 

Well, it's a (PWM - see my sig) signal from the PCM so next suspect would be wiring or connector. Quite uncommon, whatever it is.

 

I have the same issue?....cooling fans do not come on, just like the op fuses are good....power coming to the relay yet still no fan ...I will remove it tomorrow and take a closer look......so far I am very disappointed with this jag

 

Lt0302 - haven't worked any further on fan - don't really drive the car much and it's been extremely cold this winter - putting it off till spring now. Would appreciate if you keep us posted on what you find out.
