2011 Rear AC

I have a 2011 with rear ac.
Does anyone know if there are two compressors
on the van for ac? My old 2004 sprinter had two,
one for front and one for rear. Is the 2011 the same setup?
I am asking because I do not seem to get any cold air out of
the rear unit without turning on the front ac as well.
On the old van I would just use the rear ac most of the time
and it worked great, like a meat locker.
New one no cooling seems to happen without front ac on.

if it is genuine air con yes you have 2 air comp just look you will see , and the front air con button must be on but you dont have to turn front blower on i think ,also check cabin fillter on rear air con vents as this gets blocked.just checked my one was blocked took it out and washed it and dried it put back in was ok.....
