Hello all,
I have an interesting glitch going on with my 06 Denali. We bought this vehicle used about a month ago. My wife said it happened within a couple of days of buying it, but we couldn't get it to duplicate. It has come back now for the last couple of days. I will explain what is going on.
Without turning lights on:
-When I turn on the turn signals, they work fine until I depress the brakes. -The blinker then hesitates and continues functioning
With lights on:
-When I turn on the headlights, all headlights, taillights, and brake lights work fine initially.
-When I turn on the turn signals, two things happen
----they signal at a faster rate (like trying to tell me one is out)
----the mirror signal on the opposite side lights up halfway in addition to the mirror for the signal that is intended lighting up
Additionally, when the lights are turned on...
-When I depressed the brake:
----the tail lights quit being illuminated
----the brake lights do not illuminate
----the 3rd brake light does illuminate
----the turn signals quit flashing, but ...
=====the mirror signals fully illuminate and hold while braking (like the vehicle is trying to compensate for no brake lights)
=====the turn signal arrows on the dash illuminate and hold while braking as well
My initial thoughts were:
-light out somewhere
-fuse
-possible short in the wiring somewhere
I read through a couple of posts on lighting issues, and checked bulbs and fuses, but have not found anything amiss. It's possible that I have missed something. I will recheck all of the bulbs and fuses. If anyone has a specific area to target, that would be awesome.
If you have other possible reasons for this issue, I am all ears. If I can't figure it out in the next day or so, I'll take it to the shop to have them chase down the issue.
Otherwise... WTF?
Thanks,
Rok
