signals and brake lights in rear of 2006

[Ghosterbear]

My front signals and warning flashers work but my rear signals and flashers do not. And my brake lights did not work.
I changed rear brake light/flasher bulbs and replaced the indicator fuse.
Now my brake lights work but the turn signals and warning flashers only in the rear do not work????
NO trouble codes show.
Anyone ever have this happen? I have no idea!
Thanks in advance for any suggestions.

Take both rear light assemblies out and get a 12 volt test light. Ground the test light well and with the plugs disconnected from the tail light assemblies and the flashers on, check each terminal in the plug for flashing signal. If no flashing signal then you will have to check the TIPM. If you have a trailer plug, check for flashing signal there. You might need to check the turn signal switch too.

I had decided to check for voltage at signals and brake lights in rear. I did have power.
What I found at all 4 bulb positions were 4 bulbs that looked perfectly OK no burned look to them and the filaments looked brand new! So I decided to try changing out the old bulbs with the new spare ones I always carry with me. That solved my problem! All lights work OK now and I still have no idea why the bulbs that were in there stopped working.
Any of you electrical guys have any idea?
All bulbs were Sylvanias. Tail and stop were #3057. Park and turn were #3157. That is what my manual calls for in those positions.

Likely there was a bad or simply corroded connection(s) at the bulb to socket. Replacing the bulb (i.e. removing it from the connection and reconnecting it) reestablished the bad connection.

One other possibility is that removing the taillights and then putting them back in helped to reestablish a bad body to tailight ground connection.

Glad you fixed it and let the site know what fixed it.

Had same problem but not both at same time. If you look at the bulbs that you removed you will probably see on the base where the little wires extend out of the bulb that one or more will show signs of elect. arcs. The SS or what ever the bulb wires are made of evidently is not a good conductor. bg

I have had more than once where one brake light burns out and within a week, the other is out too. Must get extra current when the first bulb goes.
