The lights are on, but no ones home

[The_Hawk]

I've sent you an email through the VWWC system with an old log which should have what you need.

Based on this:

The auto scan gives you all the long coding (which is what I have sent). If you need the full Adaptation Channel Backup or LIN / Slave Modules information (as listed in the above link) that is something I can do later when I'm home from work and have some more time to spare to extract the various sub components. I would assume you want these two:

08-Auto HVAC
09-Cent. Elect

I’ve seen weird things happen with AC systems due to low pressure which can rise and fall with engine load, but electric fans???

Just had a tech here for 3.5 hours trying to diagnose it. He has no idea why it is doing this except for a faulty bcm.


Very strange.

Electrical gramlins are the worst, especially intermittent ones. Time to trade in and upgrade?

Hell no!!! We love the multivan!

As the Hawk says : If it has an engine or heartbeat it's going to cost you : Have a Merry Christmas and I hope you get it sorted .
