2013 Honda Civic Power Window Issue:

My son reported none of the windows were working on our 2013 Civic EX.

I checked the x4 20A fuses which were find so I ordered the drivers door master switch. The new switch fixed the drivers window, but none of the other windows work. I also confirm the window lock button is not on when testing the other windows.

Today I replaced the front passenger switch which did not fix the issue. I used a battery to test the motor and determined the motor is fine. I used a 12v test light but could not detect power so tested the driver switch connector and also could not detect power so I’m guessing it below 12V since the drivers window still works.

Looking to jump the window lock wires on the drivers master switch. Any one know what wires are used or have any other things to check.

 

Was there something that happened recently to the car, like an accident or aftermarket electronics added, etc.?

Power to the passenger power window switches comes through the power window relay (located in under-dash fuse/relay box). The MICU (multiplex integrated control unit, integrated into under-dash fuse box) has to send a ground to the power window relay coil; which in turn allows power to go through the relay contacts to the other non-working windows.

 

 

I used a multi meter and confirmed 12V at the connector. I also tested the motor wires in the connector and no power. I don’t think all the 3 switches went out and the new one is bad so I’m still thinking it’s the window child lock on the master switch.

Anyone have a wire diagram for the master switch so I can jump the wires to test switch?
