Default 2008 Speedometer Problem (Only works with lights on)

So I have a weird problem with my speedometer. My speedometer will not work unless I drive with my lights on for 15 to 20 mintutes.

The needle just sits at the bottom and flutters but never moves. All my other gauges work perfectly fine. Dealer said I need a new speedometer but I don't under stand why it works after I have my lights turned on for awhile.

I have already done the cluster sweep and it did not work properly as it would get stuck and not return. Also tried to deaden the entire system and that did not fix it either.

Any thoughts?

First mistake dealer...Dont ever go to the dealer again especially on here if you want our help. I would buy a used cluster online ebay or a pick a part and have it installed by myself or a shop. It's super easy to replace if your smart enough

No, I don't work for a dealership either but I and most others on here will offer assistance whether you go to a dealership or not. Offer advice for his issue and don't speak for the rest of us that are really here to help.

The electronics of the gauge are attached to a pcb(printed circuit board). Turning on your lights on activates a power line that runs many places on that board to light up the leds. Seems your PCB is going out and turning on the lights is enabling power to make it to the speedo where it's not getting it immediately during start up.

Your best bet is to get a fully functional cluster and swap it out. The mileage will be off, but you can get that reset pretty cheap at an autobody shop.
They are used to replacing gauge clusters. Or leave it and just note the difference if you ever sell your truck.

Your other option is to peel your cluster apart and look for the trace that is failing.

Good Luck!!

Just found this on ebay.

Contact the person and see if they have seen/can fix your issue. $50 is cheap!!!
