Cargo light flickering

Where are these relays located

 

The flicker is odd since we only know that the Cargo switch is left on DOOR. So my guesstimate is Body ECU is allowing path to ground (barely) and/or the Cargo relay has a weak/bad coil or a gremlin

 

Above the cab fuses, you'll need to remove the lower dash panel steering side.

 

Go here to view the removal of the panel...

Some have removed the whole relay block out thru the cubbie without removing the lower dash panel...

 

That's the "cubbie"

 

Pretty much what I said...I can "read tattoos pretty good", ya know?

 

I just took apart my panel and my drivers side carpet and padding is soaked but all the electrical seems dry

 

Snowball is getting bigger...

 

Tell me about it

 

My guess is the relay that's bad... (cheaper fix)..if it's further away (Body ECU) then that's not cheap fix. Or live without the connection to it...switch can be disconnected from the BECU

 

I just swapped the relays and the lights are still flickering

 

I did just notice it only does it when the truck is running not when the acc is on

 

So it's not the relay or the switch. Next level, without getting too expensive, the door shut pins. But if it were them the inside cab light would do similar quirk...so it's pointing again to the Body ECU...$$$
These are the related switches to the Cargo Light circuit, they also are tied into the cab illumination.

 

Cargo Switch at DOOR Body ECU manages ON/OFF...Cargo SW at ON bypasses Body ECU... Cargo SW at OFF=OFF

 

Even with the relay out it still does it when the truck is running, what could that mean

 

Magic? no..I mean it's getting juice from somewhere else...have wife step on brake as you watch the Cargo Light...

 

The brake light Illuminates and the cargo lights stay flickering

 

Maybe water in the lamp assembly...

 

I’ve had the third breaklight replaced my the dealer
