HVAC fix and nav hack 5 hour marathon last night: I finally fixed my murmuring buzzing hvac

And did the nav DVD hb lockout hack...
Hvac:
There's 2 vent motors on the passenger side...
The top motor is controlled by the mode switch, it's cam controls 2 levers and maybe 3 vents.
The cam will run off the rails causing the issue: the buzzing and less than perfect mode operation.
I removed the motor, cleaned it, rejigged the internal contacts a little, and reassembled it all.
Tip: when removing the motor assy, unscrew the forward most screw first as it's mount is thin plastic and it will break, mine might need reinforcing there sooner rather than later.
This job is difficult, I removed the DVD and I recommend removing all the pass side lower trim for ease of access.
I was working upright, mostly blind, and I'm hoping with all the trim removed I can work on my back next time.
You'll need every length of screw drivers, and a mini ratchet screw driver type socket set with extension is a good thing too.
And a ton of patience!
Write up sometime soon.

As for the DVD nav hack, as per instructions (finally comprehended), I removed a pin from an old heatsink fan and inserted it into the appropriate hole of the connector that can be seen dangling in the pic.

Nav how to with everything inc nav diagnostic mode instructionsThat wire just gets grounded to the DVD chassis. Easy! Thanks!!!

So if you are doing the handbrake lockout hack at the nav screen end, the grey wire is cut and grounded body to nav unit.
If you are lifting the center console to reveal the handbrake then you can ground the grey wire at the other end, cut the wire, ground it body to nav.
IIRC the HB nav hack allows switching the nav aux video input on the move, so eg I can switch between my SGS i9000 Torque guages and the nav.
IIRC the DVD nav hack allows input on the move, eg destination, vehicle info etc.
As usual do this at your own risk!
Why all the links? It took me months to work all this out as the info is somewhat scattered and incomplete... probably for a good reason
