I searched and read everything I could find, but I did not find any solutions. Does anyone have any idea what would cause the fans to start as soon at the car door is opened? It clearly isn't an overheating issue and I doubt a stuck thermostat would be the cause either. Possibly a relay or sensor? Any help would be greatly appreciated!

 

I have the same problem as yourself . fan kicks on Full as soon as door is opens etc without starting the engine or ignition on , common problem i have seen as i googled it up some of the older jag models suffer from same , fix was either a new thermostat , new fuse , new relay or a new modual in some cases a broken or worn wire , Mine in garage at present for diagnosis

 

Good luck with this. Too bad others that experienced this problem and started a thread never followed up with their solution. Shame on them.

 

Worn wire under front of mine good luck with yours

 

Any chance you can be more specific about where to look for the worn wire you encountered?

 

Not for now on arrival to pick mine up around 12ish today owner was unavailable out on a test drive, so i just asked the receptionist who told me front some were they had to remove the front bumper fix the wire then put back on the bumper . car drove great well felt great after driving the company small van for last month then a big problem . hit a very l;arge pot hole at 70mph was lucky to gain control and swerved of dual carrage way without being killed ( i am quite shaken just now no hard shoulder to pull into and had to swerve over 3 lanes as you may well understand . i shall ask tomorrow what side the wire problem was on but sure it was the left passengers side UK wont be on till later got a shock

 

Glad it ended well for you. Well done.

 

Thanks seems to be quite common across the range a worn wire in front harness around headlight harness all i can find out. the xf has a well know trunk wiring problem so this could be simular i have seen lots of links to older jaguar models and current same issue

 

Thanks for the suggestion of where to begin!
