For the electric problems,check the wiring into the drivers door where the hinges are,the wires can break causing your problem.If they seem OK,then you have to suspect the switch is at fault,on some Renault models it is possible to plug the passenger switch into the connections on the drivers switch,so this would be worth trying.
The heater could be either a motor fault(possibly over heated due to a blocked pollen filter),or a rheostat fault.I think there are some threads on finding and checking the rheostat on Scenics on the forum already,so if you do a search you should come up with some usefull info.
I'd rather push my Alfa than drive a BMW....
