Brake light blinks with turn signal on

Good day, new to this community and just spent the better part of an hour going through the other threads on this issue with no luck. So here is what I have, 2004 Tacoma that the right rear brake light blinks with the turn signal on, but it is very faint. When the brakes are applied, both the turn signal light and brake light blink with the brake blinking bright this time and of course, on the dash the turn signal blinks rapidly like one of the turn signal bulbs is burnt out. Same results if the lights are on or off. Inspected and fluked the connections and wires, but everything looks normal. Any suggestions or help would be appreciated.

Get a multimeter and start testing leads. Not sure how else you could diagnose. Obviously you have a wire that is making contact with another where it shouldnt. Check for frayed insulation and water intrusion, at each junction.

 

Check the trailer plug if you have one for corrosion. Pretty common for this to occur.

 

I agree with Koditten. If you have a trailer harness, something has happened to it and it will cause problems with your signal lights and brake lights. It happened to me.

 

Might also be Physical damage to the wires !!

Check the Trailer Converter box first
