Yah, those 244 tail lights can make you crazy! BTDT

You have -

cleaned the flex circuit

brand new tail assemblies

checked for bad ground, broken wires, loose conections. All OK.

You have done a lot of the right things, but there's more, naturally.

First, check the bulb holders on the lower outer lights. White one on the right side, black on the left. Check also that each has a two-filament bulb inserted correctly.

Second, turn on the park lights and set the key and shifter to have the back up lights be on. Turn on the headlights and the rear fog lights. See what lights are on, or not. On each tail light unit there is a white connector. If there is a light that should be on but isn't, wiggle that connector and see if that makes any difference.


Come back with that, more help is available.

Good Luck,

Bob
