Yes...you are bypassing the relay to test other components..It is not a fix...It is part of the diagnosis..J
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?
I personally would just replace the relays, they're 11 years old anyway. Then use your advice if the fans still did not operate...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

You will need (2) 'good' relays. 1 relay runs the fans on low speed, and the other relay runs the fans on high speed.UPDATE:
Hello, I did some dignosing on the relays and YES it was one of the relays! View attachment 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?
