Question time! So I've in the past successfully got the Passat panel (
3AD907044Q) working in the golf mk5 (dual flap motors version). All was well until my recent condenser fault where it was slow leaking but I blamed my panel wiring for the compressor failing to work - so prior to taking it to a garage to have a look I reverted the wiring back to factory so I could reinstall my mk5 climatronic panel.
Sadly in the process the panel became seriously damaged as I put it in the boot and it somehow got lodged under something heavy...
No big deal I thought, let's get a new one, so I found a Scirocco panel to replace it (
1K8907044J):
Car came back from the garage, vacuum tested and gassed up, mk5 panel makes the car ice cold so thought success was close. Prior to removing the mk5 panel again I set it on max heat and re-circulation off so as the fresh air intake flap motor would be left in fully open position when disconnected after.
The new panel lacks auto re-circulation but I just didn't rewire it back in and instead did a straight swap of pins 16 and 20 in Connector A.
Then went on to follow the usual instructions I did with the Passat panel...
These wires you’ll have to remove:
Connector C / 16 pin Brown pin 9 white/ green
Connector C / 16 pin Brown pin 10 yellow / green
Connector B / 16 pin Black pin 7 grey / green
These wires you’ll have to re-pin /change pin output
Connector C / 16 pin Brown pin 7 purple / yellow - put this to PIN10 in the 16 pin Brown connector
Connector C / 16 pin Brown pin 8 blue / red - put this to PIN9 in the 16 pin Brown connector
Connector B / 16 pin Black pin 6 green / white - put this to PIN7 in the 16 pin Black connector
So, after doing it, turned on the engine and held front air + AC as usual to do a panel re-calibration - then nothing. Blower/heater works but the radiator fans don't start up and the compressor doesn't either...
Connector A changes seem fine as it's retaining the settings on it between power cycling the car, but I suspect the fresh air flap isn't behaving so the compressor is refusing to spin up.
Any thoughts from anyone who has done the mk5 (twin flap motor) conversion to a newer panel, mk6/mk7/scirocco/passat - it shouldn't matter as the panels are all interchangable as much as I can see...
Just stumped as this worked first time using the Passat panel above and I sourced a 'rocco panel instead as it was the only one available at the time on ebay.
