if you remove the back console, youll be able to see the "machine controlboard". appro. ha;f way down and favoring the left side of circuit board youll notice a small blue relay cover(MAYBE 3/8"X1/2" in size. well just above that relay cover you see a resistor that will be physically burnt out( a real noticable burn ring around it) if this is the case you need to replace the board as well as the "wax motor" within the latch assy.
