Default Random Problem with Lights.

Everyone once in a while, the bottom light (turn signal/parking light) will just not turn on. The turning signal part always works, but I'll pull up to a car and notice that my car is 'winking' at everyone. I thought the bulb was gone, so I go to check it, works fine. This morning, the other side of the car is doing... I checked the wires and other "idiot" stuff... Electrical problem? Do the bulbs randomly work as they are going out?

Default It's a fairly common problem reported here, it's the Emergency Flasher button...

that controls the turn signals.

Default if it keeps acting up, the whole flasher button needs to be replaced.

No kidding.

There is no external "flasher".

Auid uses two relays in this button, and a bunch of electronics.
Each relay controls that particular side of the car.
Both relays are used when the flasher button is pressed.
Copper squares here.

(Don't ask how I know this, or why I have this switch apart.)

Press the 'Emergency' flasher button.
Listen closely.
Do you hear the relays clicking at the button?

This switch may be bad.

Hope it's under warranty.

I ask again: Is there any part of your car which you have not disassembled and photographed?
