I have a 2005 Ion with a sick turn signal. One of the two filaments burned out. Saturn conveniently made the replacement operation tool-free. Replaced the bulb and it still doesn't blink.
Checked the bulb and in-headlamp assembly wiring with an ohmmeter and by hooking it up to a 12 volt supply. That leaves the control circuitry.
I've heard of this happening on 2003's and 2004's. Anybody run into this on a 2005?
And last, the bulb has 2 filaments, one higher wattage than the other. Which way is it supposed to go in? The bulb is symmetrical with no polarity markings.
Thanks!
