Customer Question

I have a 2005 Trail Blazer and the right turn signal flashes very fast and the rear light does not flash. What could be the problem, the bulb is not burned out?

Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

The biggest issue this model had with the turn signal light not flashing or operating in the rear is the circuit board that the bulb inserts into.The circuit board burns out needing replaced.GM had released a bulletin or recall on the earlier model year for this vehicle here to replace this circuit board for this issue here but after looking at this info on your year it doesnt look like it applies for the free replacement.The circuit board does fail and is most common for this issue needing replaced.
