Recently the right front turn signal comes on (does not blink) when I hit the brakes. Signals work OK when not braking ... what is going on or where do I look?
Turn Signal comes on with Brakes on 2002 Toyota Tacoma
either a bad bulb or a bad ground at the socket. carefully inspect the socket for corrosion and that the bulb fits tightly.
I had already done this; no change. I found the problem - the previous owner had installed a trailer hitch (DrawTite) with a connection into the brake and turn signals. This connector block had arced to ground and fried a circuit board, plus much of the insulation had gotten brittle and come off the wires. Removed from circut - problem solved!
