2000 Windstar All brake and tail lights dead, fuse ok

Light bulbs require power and ground in order to work. The ground circuit for the left rear combination lamp is shared between the turn lamp, stop lamp and tail lamp. Because the tail light still works in that specific combination lamp, we know that the shared/common ground for that assembly is OK. The power circuit for both stop lamps (left and right) have the same origin; voltage flows from the STOP LP FUSE (15A) through the DBC RELAY (when the stop lamp switch is pressed) and then to each stop lamp via their respective circuit branches. Because the right stop lamp works, we know that the shared/common fuse, relay and switch are all OK. I'd suspect an open in the left stop lamp power supply branch and would recommending checking for voltage on the green & black wire at the left rear combination lamp assembly to confirm. Regarding the left lamp on the hatch, the wiring diagram indicates these are not stop lamps rather tail lamps only. I'd recommend installing a tail lamp bulb instead of a brake light bulb into that assembly as a first step.

Check the bulb there's also a plug you disconnect when you want to take the tailgate off

Yup! All those are right. REPLACE BOTH TAIL LIGHT ASSEMBLIES. (N.A.P.A. OEM Parts Only)...Easy (a little removal of the tail lenses...They plug right in. "Plug & Play!"

Justo change the socket or put some grease for bulbs

Check BackUp Module, generally is located in the rear quarter panel (drivers side).

Well for the license plat you might wanna check the fuse. and the brake light if one works fine then I'm sure you need a new bulb in the other side. Good luck

if the bulbs are ok! check bulb socket to see if you have power.with test light, if not make sure sockets are clean. check the bulbs first, because they are a double filiment bulb. for brakes and tail lights. did you change the correct fuse!! it is located in interior fuse box on drivers side end of dash. its on bottom left side of fuse box. its labled "stp lps". hope this helps,

Open the trunk and locate the trim door that covers the back of the drivers side tail light assembly. Open the door and locate the bulb holder. The bulb holder can be removed from the tail light assembly housing by turning counter clockwise 1/4 turn. Holding the bulb holder in one hand, press gently on the bulb and turn then bulb counter clockwise to remove. Replace with a combo bulb and reverse proceedure to re-install.

change the bulb in the tail light. And check your fuses for the license plate.

could be the socket where you put the bulb or the wire that goes to the socket. there could be no power going to the wire.

tnx 4 using fixya,
