2014 Caprice flickering headlights and dome light???
Re: 2014 Caprice flickering headlights and dome light???
There are only four RPO code based options configurable in the BCM of a 14-17 Caprice PPV.
You'll also need all of the FOBs that are for that vehicle with you so the service tech can have all of the FOBs programmed into the replacement BCM (if it really needs a new BCM).
As @Sanford suggested, you might want to check the Caprice's grounds and the ground cables.
I was also assume / suggest that if there are still any police upfitter installed devices that might control the lights of the vehicle to make sure they are removed and test the headlights again.

I am going to check the grounds and alt connections again.
I found the headlight flasher box and disconnected it and reconnected the OE wiring back together.
THANK You VERY much for your help.

Re: 2014 Caprice flickering headlights and dome light???
I had the car checked.
Every ground was checked and they are all good minimal drop between them and whatever we checked them to.
Battery is good.
Alt. is good.
And still flickering lights.

Up date
NEED HEADLIGHT wiring Diagram
I unplugged the Pass side headlight and checked to see which wire is the one acting up.
I found that the Gray wire ( #6 ) is the one pulsing

Re: 2014 Caprice flickering headlights and dome light???
Think that is going to be the parking lamps circuit. 309 Gray/Brown on the right side 709 Violet/Gray on the left side.
https://www.chiltonlibrary.com/content/ ... 601731.pdf
And just for a clue to the Pulsing. I believe the parking lamps at the taillights (that are on the same curcuit as the fronts) are LED circuit boards. If a voltage reducer of some kind has gone out on those boards might produce a voltage pulsing. Maybe unplug the tails and see if they pulsing goes away??
Oh and just watching your video.
Do you have LED headlights in there?
Led's in the Glove box or dome?
Wierd your cars voltage stayed constant and high.
Do you have the stock harmonic balance on there? OR an underdrive unit?

The signal lights start flashing at normal rate then soon after they speed up (like an old car when a bulb is out) but all lights are good. I have gotten the warning on the DIC about bad signal lights but all are working fast but working.
The lights flickering starts after a few minutes of the head lights running. NOW the big mystery is WHY they only flicker when the gear selector is in anything but parking?????
This flickering condition also effects the dome and glove box lights
The only thing I see missing in that diagram is the Dome and glove box lights
What is the position of this wire on the BCM ?
Thanks for you help

Are any of your bulbs in the taillights or headlights aftermarket LED? You taken them all out to check?Turbopowered68 wrote: ↑Tue Jan 19, 2021 6:41 pm
As far as I know the head lights are OE

The BCM positions are listed on the Diagram. Connector X4 position 6.
X4 is the black colored connector
Dome and glove box also come off the BCM:
