in my 95 bronco...the turn signal wont work when you press the brake pedal..other than that, they work....do you think it's a fuse, switch, or ground wire?..if ground wire..how hard is it to detect..and how hard to fix?...if both left and right turn signals dont work with foot on the brake...would there be 2 ground wires bad? one for each side?
if a ground wire is bad..do you have to re-wire the whole wiring harness?..how does that work?
thanks for your help
 
Check to see if the front and rear turn signal lights on both sides work when you turn them on (no brakes). If not replace the bulbs that do not light. If you still have the problem, take the vehicle to an auto electrical repair shop and have them check the cut-out switch for the turn signals. There is no need to replace the ground wires or the wiring harness.
 
I'd be looking at the turn signal switch. the brake lights cancel thru it. I have seen a few of them go bad that way on the Rangers, which is essentially the same vehicle.
