Roush intercooler problems!!

Have you verified that there is power to the “blue box”? I have to think it serves the same purpose (fan turn-on delay, relay, etc.) as the purple plastic box located in my passenger fender well.

It would be nice if someone on this board had a wiring diagram for the circuit. In the mean time, you could hook up a manual switch with a relay to turn the fans on.

I remember a guy who installed a manual switch to his fans back east. He had schematics for everything. The only reason I remember him is he changed it back becuase he burned up fans from them running and running.
I'll see if I can find his info.

what would be the best way to check the power on the blue box?
the reason i replaced the blue box is that my slef and joe at chciane thought it would be the next logical step, i was thinking of wiring it up to a switch but id like to have it work the right way with the money ive spent on the box and the wiring harness

Again, a wiring diagram would be most helpful. The box has to get power with the ignition on. It is a matter of determining which wire it is. It should also have a ground, so you can check the continuity.

Was there anything out of the ordinary that led up to this problem? When the box failed on our car, I think it was actually the result of previous work Chicane did. I am almost certain they inadvertently shorted out the IC board in the box.

My suggestion for a manual switch is for a temporary fix only, btw. Do it down and dirty cheap until you can get the real problem sorted out.
