Drivers side window problem

[sbg35c]

I have a 03 G35 coupe. The drivers side window will not operate sometimes. Somedays it works fine others nothing. Also now the controlls for the radio and heater/air will not work either. They work I just cannot change them. I can change the radio using the steering wheel controls but there is no display. I think it may have something to do with the controller Assembly located under the fuse block on the drivers side. Does anyone know what the controller does? Thanks for any help.

Radio/AC is a common issue, can get it fixed by electronics shop that knows what they are doing.

For the window, never heard of one going in and out, shouldn't be related to the Radio/AC. I would guess its the window motor or regulator that needs to be replaced.

Wheres the window regulator located?

FSM is the quickest way to find it. Would be behind the 2 door panels, main door panel and then the metal sheet covering all the insides of the door.
