Do you have the 2006 Service Manual (2006-LX-SM.pdf)? Section 8W will give you the complete wiring diagrams. It is 325Mb in size. If you do you can troubleshoot the window wiring. I had a 2006 LX and still have the manual.
If not, do a Google search for 2006-LX-SM.pdf
One common problem is a broken wire, or wires, in the cable that runs from the body to the front doors.
Do you have a volt-ohmmeter? If so what measurements have you made.
What I do is print out the diagrams and use a red felt tip to trace out the circuits. It might be a missing round too. Good luck. Bob.
Ok. glad you got it. The diagrams are complete so you should be able to trace out the path to the windows and the mirror. Good luck. Did you check out for 12V at each side of all fuses? The circuit breaker should also be checked. If you need any more help let me know. Bob.
