I have lost all functions on the master driver door switch. No response for any window, no response for power mirrors, and no response for window lockout button. However, the illumination works as all buttons light up fine. Replaced the entire switch unit and same status.

Independent passenger windows all work fine, with only the auto close function not working. Auto open works though.

I have done everything I can think of, (Disconnect drivers mirror, disconnect battery for an hour, disconnect both driver and passenger mirror, cleaned contacts of switches, checked fuses - all were testing good, replaced all 30 amp fuses with brand new ones anyways, etc.)

Stumped. Mirrors seem to have power - chromatic functions and heat work fine, just cannot fold or adjust electronically from the switch console.

Also, window regulator and motor are working, as I can open and close all 4 windows and sunroof with the keyfob and door lock with key.

Any help or suggestions is appreciated. Thank you.
