You REALLY don't want to hear it, do you?

The flashing of your turn signals (and hazards or four-ways) is a function of the BCM.

Here's a photo of the big box next to the battery and the modules in it. Grab that middle module and perform your fix!
(No, there is no schematic of that module that I know of. I mean, the tuners may have one, but us mere mortals dont.)


Now, here's the page from the always-marginally-accurate-and-always-incomplete POS of a service manual we are given, this is as detailed as it gets.
The "flasher" is in that box called "Body Control Module" down near the bottom of the photo. That's it -that's all they give us.
As you have been told; You may reverse-engineer it but if you do, PLEASE come back and tell us how you did it, cause we cant'/haven't/don't want to try/dont really care.

But if you pull this one off, I'll sticky the thread where you make our day, cause you may not be the only one interested in this - and I'd like to see SOMEONE come up
with more information on the BCM.
