I have tested the fan and it works on both speeds; replaced the ECT sensor and installed a new radiator about 3 months ago due to a leak. What else could be casuing the fan not to operate. Any help would be appreciated. I need to complete this job soon for my wife to go back to work.
Thanks,

Hello and thanks for the donation!

Test out your Cooling Fan Power Relay, located on the top of left ront wheelwell, in the engine compartment fuse block. Also test Cooling Fan Relay located next to the power relay.

I located and tested the fan power relay but I am not sure about where the cooling fan relay is. There are two green relays next to each other that are 40 amp. I switched them and they still worked the same. ANy other suggestions for why my fan won't come on?

Check 15-amp ENGINE fuse in the interior fuse panel. Also test 40-amp COOLING FAN fuse in the main fuse junction panel. Let me know if either fuse is blown.

Ok, you either have faulty wiring or a faulty fan switch. Follow the diagnostic steps below to pinpoint the correct culprit.

Thanks for all of your help. I am still not able to locate the relays that I need to check. I thought I found them, but I "think" they were 40 amp fuses and not the relays. Can you help me better understand what and where to look for the relays and how to test them easily? Thanks again, and sorry for any confusion, since I am just a backyard mechanic trying to save a couple bucks.

Sure, no problem. Is this the 1.8L or 1.9L engine?

Okay, it will be located inside of the engine fuse block (circled below). It will have either part # F02Z-14N089B OR # E92Z-14526C . This is the best way to make certain you find the correct one. You can learn how to test a relay on our "How to Repair or Service" page , linked below..

The relay should look similar to the picture below and will either have 2 or 4 prongs, the color may differ though..

I found a black what looks like a relay inside the fuse box but the only numbers on it are H270
DC12V20A
5J10
None of the numbers you show are on it. This is the only plug in inside of the fuse box ad it has 4 prongs
It says it is the fuel injection relay?
