Left front/back turn signals flashing rapidly after one or two seconds after headlight assembly change

Hi,

When this happens, one of the bulbs is burned out or not connected. This is designed into the vehicle to allow the driver to know there is a problem.

Turn the signals on and check around the vehicle to see if one isn't flashing or working. Even though they flash fast, they should still be working on the exterior.

I attached one section from the wiring schematic for you to look at and see. Note there are three lights on each side of the front that ties into the signals. If any one of them is bad, it will cause this to happen. Also, I know some of these had signal lights on the mirrors, so check that as well.

Let me know what you find. If you have additional questions, let me know.

Take care,
Joe

Thanks for the quick reply. All bulbs look good. Front and back. Everything looks normal until the lights start blinking quickly. Here are a couple video's:

Hi,

Something isn't making a connection. I see the working, but there has to be an open at some point. Open the hood and inspect the connections to the lights. Also, make sure the white wire (ground in pic) is good.

With the lights on, move the wiring slowly around to see if anything changes.

Let me know
Joe
