Take out fuse F15 from engine bay, if it stops clicking, put it back and unplug the ACE ECU(behind glovebox) ... if then stops it means the ACE ECU gives a false command.... a good start would be to plug in a tester and scan the ACE. ... if the relay will click even with the fuse out we'll speak again.
