Marker lights and tail lights not working

[Podsy]

Hey guys,

I have a questions. I bought new headlight housings the other day and installed them on my 2015 Silverado Crew cab.

After install I started the truck and they headlights worked fine. The side markers did not work. Come to find out they didnt ship them with bulbs in the side markers. No problem right just put the side marker bulbs in and we should be good.

Well I did that and now the side marker lights do not come on and the tail lights do not come on either.

I put the stock housings back in and still nothing works.

Here is the kicker though. When I use my key fob to unlock or lock the doors all the lights flash like they should including the side markers.

When the truck is running it shows that the running lights are on via the dash. But the lights do not come on.

I have disconnected the battery and tried turning the to the on position with the battery disconnected and nothing seems to fix the issue.

 

Any help would be great as I am at a loss at this point.

I have a service appointment set for tomorrow morning but really dont want to bring it in for them to flash the CPU.

I should also add that the brake lights and the blinkers all work like they should its just the running lights that dont come one. They do flash for lock and unlock.

Its like the truck thinks they are on but its not sending a signal to turn them on.

Did you ever find a resolution for this? I have the same issue.
