Both front Power windows not working, rear both are fine
Sonata 2015 Sport
Both front power windows are not responding. They both went bad at basically the same time (I used them 2 days ago; no issues. Today neither works. Both are closed). No sounds are heard when pressing the button. Both rear ones work fine. The lock button works too (on the rear windows). Fuses are all good (absolutely all fuses checked, not just those related to the power windows). I understand the motor or switches could be wrong, but before I start taking the trim apart, anything else I could check? I find it unlikely that both motors/switches would have went bad at the same time. |
Sometimes a wire will break/separate in the harness where the harness flexes at the driver's door hinge area. If you can't find any other cause you might try moving the harness while the window switch is depressed and see if you get any kind of response. Of course you can open the harness and pull on each wire .If one feels rubbery , the conductor inside may be broken, which will need to be repaired..

If you have power then I would check for grounds
May have a bad ground?? |

Would you tell us how you checked the harness?
Did you cut it open and actually check each wire? If not, you are only doing part of the job. It is a circular circuit and if any one part is open , nothing on it will work. |

That's exactly what I'm doing. Your quote is not quite accurate though ;)

Meanwhile I took off the door panel and checked that I'm getting 12V to the main switch and also verified the ground signal. |
I took the door panel off and I'd like to check all the wires, but I can't find the connector diagrams for the Sonata 2015.
I was only able to find the 2011-2014 ones (see here) The 2015 one I found (see here) does not show the connector wiring. Any ideas where to find this? The connector is *not* the same, so I cannot use the older year. |
