Seriously, the vehicle security module controls the auto headlight function, looking at the diagram I do not see a connection to the turn signals
unless something is robbing enough power to make the relays for the headlights drop out

Do the signal lights seem the same brightness on both sides, front and rear?

First time I have ever seen this used in a possibly applicable scenario! :woot

Might be the cluster.

Hey now I'm bald not blonde.

 

Couldn't help myself ...scroll up and read what I posted about the security module

 

So I just went out and checked, and this is really annoying, but everything is working fine now.

 

Here is a diagram for 2004, not sure if there were any changes on the light circuit

 

Thank you Hydro. I guess I know what I'm doing this weekend.

 

Are both sides of the blinkers the same brightness on all lights?
possible short in one of the bulbs or harness -- trailer plug

 

Yes, they are the same brightness. Now I know how my faculty members feel when they have computer problems and when I get there and there isn't a problem.

 

Last Spring I started experiencing odd turn signal and headlight issues. It turned out to be the turn signal combination switch.

I removed the switch and carefully took it apart. The metal traces inside had lots of oxidation and the grease inside had become contaminated with dirt and dust over the years causing a short. Brake cleaner and Q-tips got everything shiny and clean. I reassembled the switch with plenty of dielectric grease on the metal traces and other parts that had it when disassembled.

If you do decide to take your combination switch apart, move slowly and pay attention to the springs, detente balls, and other pieces inside that will come out. It took me three times to get it together correctly. The dielectric grease helped stick things in place and eased reassembly.

Good luck
