I drove round trip 7 hours to pick up my Grenadier. In the dealer lot the AC was freezing when they were going over all the features. On the way home the AC stops working after about one hour. Not happy. It was a long drive and a logistical nightmare for me to get back to the dealer anytime...

Anyone managed to manually control the blower motor like the Webasto unit does? Any info on wiring? This is from their official pictures:

So after a little investigation this morning, here is where the air goes on the different settings on my Grenadier HVAC controls. I'll take the trace air flow to be just where the damper flaps are leaking a little. I hope this helps some others try and work out how to operate the controls...
