Nissan Repair: 2001 Xterra power window, diagnostic check, smart control

Question
My passenger side window stopped functioning, dealer says I need to replace entire smart control center, estimated at $550.  Does this sound right to you?  They were able to get the window up, but now unable to power any of the windows after the diagnostic check.  What are your thoughts?

Answer
Kathy, I would think the master switch on the drivers door.  Under $100 bucks for the part and a phillips screwdriver.  Unplug the connector under it and replace with the new one.  Just need to take the screw out of the door pull cup under the little plug and pull up on the back of the switch assembly and lift up and back.
