The Cooling Fan High & Lo Speed Relays are located in front of the LH fender apron, left of air cleaner assembly.
I apologize for the delay in getting to your question.
The two relays are located side by side inbetween the air cleaner and the driver's side inner fender. You may need to remove part of the air cleaner to gain access to them. Please refer to the picture below. I hope this helps!!
Finally, someone that knew the right answer! Thanks...But it took so long to get an answer from you, my husband traced the wires and found it himself.
I am so sorry that it took so long. Was he able to find the cause of your concern? If you need any further assistance please don't hesitate to ask and I will be more than happy to assist you.
The radiator fan is not coming on and the car overheats when I am stopped. He replaced the sensor on the engine block, but still not working. He tested the fan on both speeds and it worked fine. So he took out the relays. We have checked online ford parts and went to all of the local auto parts stores and the only relay we can find is the low speed. However, we don't even know for sure if the relays are bad since they want 100 bucks to test them. Ugh....Replacing them will also cost about 100 bucks "if" we can find the part.
Thanks again for all your help!
Well perhaps I can assist you and maybe help save some of that money. Your husband has most likely checked these but see if you can talk him into checking one more time just to make sure. There are a total of 3 relays for the cooling fan. Those 3 relays have tow different fuses that they rely on for power. The first one is a small 15 amp fuse in the fuse panel located inside the car. It will be labled Engine. The second fuse is a large 40 amp fuse located in the fuse panel located under the hood. It will be labled cooling fan. If either one of these fuses are blown, none of the relays will operate. Once these are checked, let me know the outcome and I can walk your husband through the process to test the relays. The only tool really necessary to test relays is a simple test light and possibly a jumper wire. We will cover more on that after we check the fuses.
Talk to you then!
Absolutely! Refer to this posting and look next to my name to make sure that I am online. Otherwise another expert will attempt to assist you and I will be locked out. Enjoy your trip and we will talk in a week or so!
