FUSE FOR ELECTRIC DOOR LOCKS - 2000 Saturn Ls 4dr Sedan

Look at the wire harness on hinge side of rear door. The orange wire is hot all the time, fuse protected. There may be two orange wires, doesn't matter, check them both for voltage.Use a test light to check for voltage. Also, check ground. Ground wire is black. See the rrdr mdl fuse, it supplies voltage to left and right rear door modules, according to my info.

None of the doors lock or unlock ?

Replace the door lock actuator .or test the electrical circuit . Do you know how to test automotive electrical circuit's ? If not , suggest you take it to a qualified repair shop.

No the rear door latch is not electric....but does have a electric lock which is fuse 17 in the inside fuse panel....not the one under the hood. The rear lift glass is controlled by electric and is in the same circuit fuse 17. Good Luck

Do the windows work? Does the door lock work on either front door?

Fuses should be labeled at fuse blocks. Check fuses in passenger compartment and under the hood fuse block

no. 10

check the dome light fuse or electric lock fuse, sounds like they might be one in the same.

Check fuse #14, in the fuse panel on the inside drivers side.
