Does the VX have a climate control specific built-in fault finding system like the VR-VS does? / Why are my vents not working?

[RiffRaffMama]

I've just discovered the VR-VS has a really nifty climate control fault finding system (see attached PDF). Does the VX have something like that? Or only that generalised fault code thing with the Mode+up/down button procedure? The VR-VS one walks through a check of every function of the climate control like each individual temperature sensor and solenoid, where I think the VX system just says "Quick, count the flashes... code 23? Oh that's your climate control. Yes, that's all the clues you get. Have fun." Because it'd be super awesome if it just told me specifically why air is only coming out the windscreen vents all of a sudden. And no, it's not that thing where the windscreen vent flap thing gets stuck - I've had that before in a different car and it has a very specific sound that I'm not experiencing.

Have you tested the one valve & hoses that comes of the back of the inlet manifold?

Nope. Don't know where to start. There was a little hose that had blown off its outlet, but I'm pretty sure that was related to my gas system. Whatever it was, reconnecting it did nothing for my vents.

What am I searching? "VT Calais climate control diagnostics"?

There is 3 hoses together, one for the vacuum hose for the brakes, another for the hvac, forget what the other is called?
Have another look.

If that hose comes of, it will default to the screen.

Check the Vac solenoids,
And the circuit board they are fixed to,
My VY climate control would not work on the dash vents,
Found a negative track had corroded, due to a water leak in through the HVAC air intake.
Soldered a surface mounted wire from point to point,
All fixed.

yeah
in the vt-vz manual

 

[RiffRaffMama]

ah ok. That clickable manual, you mean?

I think you need to have a Tech2 (or equivalent) to display ECC problem codes. I have personally only ever used a (compatible) Tech2 for this purpose. You can use the VT/VZ manual to find out how to resolve the problems identified by the codes, but you need to be able to display the codes in the first place.
