The most likely candidates are a bad multifunction switch or a bad ground

Help I thought the problem was solved, but its backkkkk.
-With the lights on uncranked all taillights work except the orange section of the left one.
-With the lights and engine on the left turn signal will work but the right one will not; but he flashers work. If i turn the lights off everything works fine.
I have changed all bulbs, changed the multi-switch ( ford part no F77B13K359AA for a 96 Explorer), checked both rear plug s for current (brown Wires). Help I'm stuck and would appreciate any help or advice. Thanks
