REAR parking lights

[jmaclean523]

The rear parking lights don't work. Bulbs look ok, fuse good, front parking lights work. Had the fuel pump replaced recently. The truck is used mainly on week-ends during the day so not sure when the tail lights stopped working. The signal and brake lights work too. Ideas ?

Thanks in advance.

Maybe new connector plates, you can get both of them for probably $30 shipped.

If they're both out at the same time, I doubt it's the circuit boards, though it wouldn't hurt to take a toothbrush to them to clean them out. Look for a wiring fault, especially in the trailor harness wiring. That's my guess.
