Hello and welcome!

My name isCustomerand I can assist you with your question.

Expert:  AMEDEE replied 3 months ago.

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?

Customer: replied 3 months ago.
i am, the one on the radiator. and the lines have power
Customer: replied 3 months ago.
no i dont have a diagram
Expert:  AMEDEE replied 3 months ago.

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?

Customer: replied 3 months ago.
The fan isnt turning on at all. All i know is that my headlights and everything else is turning on. Its a brand new never been used before fan, and my fuses are fine.
So what should be creating a problem?
Expert:  AMEDEE replied 3 months ago.

How do you know it is not coming on? What are you experiencing? Overheating or poor AC performance?

Customer: replied 3 months ago.
i turn my car on to let it run, and its not turning on when i turn my ac on or when it gets hot enough to actually start running, but i do have air coming into the car through the vents

hello?
Expert:  AMEDEE replied 3 months ago.

YES, I am here

Expert:  AMEDEE replied 3 months ago.

Got it! Thank you for that information. Let me pull a wiring diagram for you. One minute

Customer: replied 3 months ago.
i think it might be my R15 bus fuse
Expert:  AMEDEE replied 3 months ago.

Have you checked the fuse or the cooling fan relay?

Customer: replied 3 months ago.
its a brand new fan. Its fine. And my fuses are all working and not brokem
Expert:  AMEDEE replied 3 months ago.

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?

Customer: replied 3 months ago.
i hear the relay click
Expert:  AMEDEE replied 3 months ago.

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.

Expert:  AMEDEE replied 3 months ago.

Here is a wiring diagram for this circuit.

Customer: replied 3 months ago.
how do i test for the voltage? and only 1 relay was clicking but there is two there. should the other one click?
Expert:  AMEDEE replied 3 months ago.

Which one was clicking? You should have two cooling fans and two cooling fan relays. Which fan is not working?

Customer: replied 3 months ago.
for some reason neither of the fans work.
Expert:  AMEDEE replied 3 months ago.

Are either of the fan relays clicking? Or is it a different relay that is clicking?

Customer: replied 3 months ago.
my R2 relay clicks and the R1 does not click. And the fuses all look good
Expert:  AMEDEE replied 3 months ago.

Are they labeled K45 and K46?

Customer: replied 3 months ago.
im not finding anything labled with a K. only F and R
the Rs are under the hood and the Fs are on driver side behind pannel
Expert:  AMEDEE replied 3 months ago.

Let me send you a diagram of these.. one sec.

Expert:  AMEDEE replied 3 months ago.

It is the two relays on the left side.

Customer: replied 3 months ago.
ahah! those were the ones that i was talking about! I just went up to the auto store to get new ones of each
Expert:  AMEDEE replied 3 months ago.

Excellent! So do those relays click when the fans should come on (when the engine gets hot and when the AC is turned on)?

Customer: replied 3 months ago.
they were only clicking at first. It was very random, and then it stopped completely. So i thought i might need new ones
Expert:  AMEDEE replied 3 months ago.

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.

Customer: replied 3 months ago.
oh alright..hmm..where does it get power at? and where should there be a ground?
Expert:  AMEDEE replied 3 months ago.

Thats why I sent you the wiring diagram. It shows where those relays get power and ground from.

Customer: replied 3 months ago.
i cant seem to find it
