  • Q:

    The left turn signal works intermittently on our 2007 Trail Blazer.It has the 4.2 engine.It is the base model.Would this be the "relay" or "module" that controls the signal ? I believe the relay/module is located under the left panel below the steering column. Right signal works fine.When the left signal goes out, the 4 way flashers only work on the right side. When the left signal works, all the lights flash when 4 ways are used.
