same problem, it was the rubber mat between the power window button and the receiver / cct board in the driver control panel for me.
one day i had no power locks or driver window? weird. i checked everything! did every kind of cable pull off the battery, asked mechanics?
I pulled the control panel out and put it back together, then with dielectric grease on the plugs and the fuses were good.? i thought it was the fob so i messed with that for a while, changed modes.
then pulled panel out again and brought it inside and was looking at how it works and noticed the rubber mat was sort of flapping a bit at one end. i pulled it right off and had a look. because the mat wasn't on properly the window and button relays were missing their target. put it back securely and put it all back together, put it back in the car and bam!! working!
