Both rear turn signal lights blink at same time. Sign In

When I use Right or Left turn Signal both rear lights blink. They were working fine two weeks ago. Front signals work OK....
I have checked both bulbs and cleaned the bulb sockets with steel wool. They both look OK.
Any help is appreciated.

Somehow the rear turn signal circuits are crossed into each other. You should inspect the wiring for the rear turn signals.

What happens when the emergency flasher is on? Does the truck have a flasher can for the turn signal and a second for the emergency flash? If they are the same can you swap the cans and see if the problem is one of the flash unit cans.

Bad flasher will either make turn signal lamps stay on or not work at all. They don't cause the front signals to work fine while the rear signals are both flashing at the same time when using the turn signals.

Yeahhh!!! I checked the towing harness plug, and sure enough it was touching metal and grounded out.
All is well now. Thank You All a BUNCH for the help.....
