My blinkers did not work ~ 5% of the time, and was diagnosed from the Dealor as a defective 4-way flasher sensor. The cost of the sensor is nominal, but they want $400+ to replace it (4+hrs labor). Does anyone know an easy way / optional to do this? Seems like way to much labor for a sensor.

 

The Shop manual shows that you need to take the whole top of the dash off. But I am sure someone will chime in with a better way. Here is the manuals text.


The hazard lamp flasher is integrated into the hazard warning switch. Refer to Hazard Warning Switch Replacement - On Vehicle .

Don't do it!!! Don't pay $400 for something you can do in an hour. I just did mine, took an hour going slow. There is a trick, you don't have to remove the dash. Someone will have the link or you can search for Hazard replacement or something similar here. The part is about $25 or $30 through Gene Culley at gmpartshouse.com.

 

I spoke too fast, here's the link to the fix.

These are the same direction I used to fix mine. I found to make it easier to put the new hazard in, I used my left hand to slide up behind the ignition. There is a small gap that if you forearms are not huge can fit through. The space is created when the console cover is removed.
