I am troubleshooting my wifes Alero. I already suspect this to either be the hazard relay or the turn signal relay. But I am unsure and would really like some guidance. The turn signal is intermitant, it works sometimes and sometimes it doesnt. Playing with the signal lever does nothing, the light bulbs are all good, when the signal does not work if I press the hazard button it seems to almost reset the system and allows the turn signal to start working. This however does not work everytime, but with some manupulating of the hazard button it will work out, it is a very tempermental discrepancy. What are my options? I was beggining to think it might even be in the steering column but I would rather not get into that immediatly seeing how it is more costly and time consuming. I look forward to seeing what you have to say.
You'll need a new hazard warning switch. For what ever reason, the idiots at Oldsmobile combines a single flasher internal to the Hazard switch, which now replaces both the old style Turn Signal Flasher & the Hazard Flasher.
This new style integral flasher is not independently serviceable.
Note: Lights flashing at twice the normal rate indicates a bulb is in need of replacement.
Here's the procedure for changing the hazard switch.
