yea get the wiring diagram and see what actually decides when to turn them on and make sure that is still functional. is it the computer the temp sensor or whatever i would also check those fan relays and make sure that they have power are still functional. just because they click if they are still moving doesnt mean that they are still making a connection and if there is no power for them to switch it really doesnt matter if they are functional or not as nothing will happen anyway. -- if at first you dont succeed youre not cut out for skydiving i changed the temperature sensor and they still do not work. any other suggestions thanks jaywd2 .
