I have a 2011 accord coupe EX. I just swapped out the master power window switch due to a broken window button. The 2 window buttons, as well as the window lock button, now work fine. However, the door lock/unlock button does not work at all, either locking or unlocking. I plugged the old unit back in, and the lock feature worked? did i get a defective unit??? any advice would be appreciated!
