2005 CL65 - Heater core bypass



..no heat
I took it to a mechanic who I think have been taking me for a ride or she made me replace the water pump the thermostat auxiliary pump etc etc
And still no heat and I got suspicious.
This luck would have it I had to replace the windshield plastic cowl..
Lo and behold it appears that both heater cores have been... bypassed..
Am I missing something?
Am I wrong to assume that with both aluminum pipes left and right disconnected there's no way I can get heat in the cabin.. right??
Pls see pics.
PLEASE SHARE PICS of the normal setup so that I can determine what to do next.
Thanks
