rear hatch no open by the switch

[yukonrrican]

I have a Yukon GT 1997. Recently the rear hatch stop open by the dash push button. Verify the actuator and the switch and both works properly. Test the connector with 4 cables who connect to the switch and none has 12V. Jump 12V from the rear wiper switch and the hatch open., so the rear hatch 12v supply fail.

Where is the fuse of this?

Thanks in advance
