Try the 20A "DR/LCK" fuse in the main fuse box under the hood.
If that doesn't work then try the 30A "POWER" fuse, in the driver's side inside fuse box, for the Back Door ECU but this may take out other circuits.
If you don't have the manual toyota.com has them in pdf format.
Thanx
Tried both of those prior to posting...
Any other suggestions?
