re: How to disable the light out indicator
I found this about the flasher location.
Turning Signal Flasher is under the hood in the drivers side fuse box. When you remove the cover from the fuse box you will see the fuses but no relays / flashers. You must then remove a second cover. The snaps are along the side of the box.
Is there a electronic instead of thermal flasher to correct the fast blinkers? I have that in the Buick so the turn signals flash normal.
