When I signal to turn left, both the right and left turn signal flash in rear of car. The front turn signal bulbs work fine. Turn signal switch all ready replaced, rear wire-harness new also. Break light work fine, flashers work fine. The right turn signal works great also when turning right. Please help.....

EVERY light bulb/function related to this (ts/brake/flashers) works good/correct with the exception of the stalk down it fires both (L&R) rear ts filaments? Pull apart the TS/brake pull apart electrical harness below the steering column and access the wiring colors at www.mymopar.com and w your VOM see if the ts sw is (incorrectly) sending fire out to both left and right ts/brake light large filaments when the stalk is down for a left turn
