Hello and welcome!My name isCustomerand I can assist you with your question.
Your talking about the cooling fan under the hood correct? Have you checked for power going to the fan? Do you have a wiring daigram of this circuit?
Thank you for that information. Which wire has power? Have you checked for a ground to the fan?
Does the fan come on when the engine gets hot? Does it come on when when you turn the AC on?
How do you know it is not coming on? What are you experiencing? Overheating or poor AC performance?
YES, I am here
Got it! Thank you for that information. Let me pull a wiring diagram for you. One minute
Have you checked the fuse or the cooling fan relay?
There are three fuses that are needed for this fan to work.. also, the cooling fan relay needs to be working. Do you hear the relay click?
Ok, good! So there is a 30 amp fuse (F2). Check to be sure this fuse has battery voltage on it when the relay clicks.
Here is a wiring diagram for this circuit.
Which one was clicking? You should have two cooling fans and two cooling fan relays. Which fan is not working?
Are either of the fan relays clicking? Or is it a different relay that is clicking?
Are they labeled K45 and K46?
Let me send you a diagram of these.. one sec.
It is the two relays on the left side.
Excellent! So do those relays click when the fans should come on (when the engine gets hot and when the AC is turned on)?
Relays usually dont go bad. If anything, they are missing an input preventing them from operating. For exmaple, they need power and ground to work.
Thats why I sent you the wiring diagram. It shows where those relays get power and ground from.
