95 tacoma- when left or right signal is put on ,BOTH signals flash at the same time??

Whats the problem. A ground problem. yesterday i put on my signal and both arrows on the dash flash at the same time. I checked the tailights and they are both flashing , when only one signal is put on??????

 

Had this issue on my XJ. Was from a bad hazard switch. Don't know of this is relevant to the Tacomas.

 

Do you have a trailer plug? This sounds like a corroded plug backfeeding voltage to the system.

Check the plug.

 

What about the front turn signals?

 

sounds like a faulty flasher, this flasher operates both hazard and turn signals

 

Had the same issue on my Silverado. It was the flasher relay under the dash. About $50 and 15 minutes made it all good.

 

Check your bulbs too have had that when bulb is defunct. Just a thought.
