Hello everyone!

Turned out I have a FBH on my 05 4.2 supercharged which seems to be not operational anyway (the fan goes everytime you open/close a door and I've read that is a symptom its failing its pretest and then not working hence of it, and also the changeover valve was left disconnected by previous owner so I guess that was the reason).

Is there a procedure in SDD that can confirm its operating status?

But most importantly - has anyone gone through a route of by-passing it? I don't see much point of it anyway, at least from my perspective (might be something I'm missing hence can be proven wrong), and I don't have the remote anyway so...

Any info would be much appreciated!

Thanks in advance!
