Yes...you are bypassing the relay to test other components..It is not a fix...It is part of the diagnosis..J

Yes! So basically the relay will be bypassed, at which time, IF the fan should come on when you start the car, you can effectively deduct that the relay is in fact, not working properly!

Umm, surely this will only determine that the fans and so on are OK. To determine if the relays are working (or not) you'd need to see if the ECU is delivering 12v to turn the relay on?

So there's another step (IMHO) to determine if the relays are good or not.

One of these can be incredibly useful

I personally would just replace the relays, they're 11 years old anyway. Then use your advice if the fans still did not operate...

Meh. They're just switches. They tend to either work or not. (IME)

UPDATE:
Hello, I did some dignosing on the relays and YES it was one of the relays!
132753

it was the middle 50amp relay in the far left. The bottom 2 are for the fans. And the middle relay was faulty. I switch the relay so I put the button relay to the middle and started the car, and my fans started working. Does not overheat anymore. But my question is, what is the relay for the bottom anyway?

You will need (2) 'good' relays. 1 relay runs the fans on low speed, and the other relay runs the fans on high speed.

2 of the 3 large relays are for the fans...The other large relay is for the secondary air injection pump. Wouldn't to just replace all 3...You don't need Maserati relays..We use suspension compressor relays for a 2004 Range Rover....Jason

I had an 09 GT and I had to replace the cooling fan resistor a couple of times. They are ceramic and can crack. Easy DIY. I don't have the part number anymore, but it is located in the center, below the 2 fans. Just 2 screws and a plug to disconnect once you jack it up.
