Please do a little checking on seeking out parasitic drains. Pulling fuses is not the way to go with today's vehicles.
Some systems reset the minute the fuse is pulled and when reinstalled will show nothing.
Some of the procedure is to activate or deactivate certain circuits , lower the driver's side window, close the door, and measure voltage drop across all fuses without disconnecting anything. That is the recommended way to pin them down.There is a whole table of readings to use and that is why you might consider having a good tech check it out.
There have been instances where another vehicle (Home in the garage) was parked next to the problem vehicle and kept waking up modules in the problem vehicle.
There are more weird things going on these days and today's vehicles are susceptible to all sorts of electronic interference.
