My sons 86 GT's turn signal does not turn off after a left hand turn. It turns off after a right hand turn, just not left. It's been awhile, but I believe there is some plastic piece in the steering column that the turn signal stalk plugs into, that I will have to replace. Is this correct?
My turn signal in my 88 wouldn't shut off after either turn, and I later realized that my brakes lights weren't working unless the lever was in a certain position. I ended up replacing the whole turn signal switch - there was only one connection to plug in under the dash. My switch was broken inside the column, with the metal cam/tang? piece broke off. Once the wheel is off and the lock plate, the only hard part is getting the connector down the column. You may or may not have to take off the brace under the dash. So you'll just need a steering wheel puller, and a lock plate compressor. One hour tops. Hazards = one screw, turn signal switch has three screws I think, so it only will go in one way I believe.
