The lights are on, but no ones home

[ozgti]

Something funky has happened with my 2011 multivan. The central convenience unit has either given up the ghost or is playing silly buggers.

The bus has been in for unrelated work, and has returned twice now, with no hvac. The lights are on, but nothing comes out. The first time, they happened to recode it back to a similar van and it worked. I haven't touched the coding, nor have they and now it is doing the same, but the coding hasn't changed. Now my remote doesn't work. I have to lock/unlock using the key.

Any ideas? They are trying to source another unit, hut with the weather hitting some serious temps tomorrow... I need ac!!

Sounds like it’s the dealers problem and not yours, what are they offering in a way to overcome this problem?

What dealer??

You mentioned “in for unrelated work”, I assumed dealer was doing the unrelated work. Maybe take it back to where it was last worked on and ask them?

Interestingly, if I squirt the windscreen wiper, the hvac works. Downside, was he bottle drains in 3 minutes and my rear wiper stopped working.

Does anyone have a central convenience unit log for a 2011 multivan? Ie long coding and what unit it is supposed to be?

That's odd on the wipers given they should run forever pretty much, the water pump on the otherhand isn't best to run for long periods.

As for a log, I've got the 2010 T5.1 Multi I could pull a dump from if you still needed it.

They are sorting it, but I needed the hvac to work today.. 45*c in Windsor today. Driving a multivan with no ac on a day like this?? Killed me!

Had to replace front electric motor fan brushes twice in my previous 08 Highline,

But the fan works when the washers are active.

If you could. The shop just tried a different bcm and it's wiped all the codes so when it was plugged in, the fan worked, but as soon as he coded the other stuff in, the fan stopped...

But now the remote works. BUT NOT the fans.
