Cluster fuse drawing power

[paulywally]

Fuse number 2 in the interior fuse panel is drawing .35 of an amp and is killing my batteries. Any ideas? Anyone else have these problems.
Is the cluster fubared?
I heard there should only .05 of an amp draw, and it is like .40 or .5 of an amp until i pull the cluster fuse.
Any ideas?

Have a total of .28 amps draw on my system. Found this to where it's coming from. Still haven't figured out a solution. Would recommend looking for some chaffed or shorted wires or a bad relay if there is one (I don't remember if there is or not).

.17 amp draw off fuse #19 (BSM/4x4Module)
.1 amp draw off fuse #35 (Instrument Cluster)

I just discovered I am having the same problem!! My fuse #2 "Cluster" is pulling .59 amps.

Can someone please help??

I just had to replace my FICM ($1700 total bill) and believe all the dead/low battery instances lately killed it.

Why is the cluster causing such a drain and how does one fix it??

Thanks in advance.

In the same boat. Fuse 2 & 35 pulling .4 amps when truck is off... Any ideas or solutions?

Same here, mine is drawing .44A at key off. I pull the #2 "cluster fuse and draw drops to .01 (next to nothing).
Has anyone figured this one out yet?

I ended up just putting an in-line switch with an in-line fuse into fuse #2's spot. Temporary fix but it works for now.

I've read that it's the battery saver relay thats built into the cluster. I've torn into the cluster but I can't figure it out.

How long did you wait after you hooked up the test to take the readings? You are supposed to wait 45 minutes. This allows all of the modules to go to sleep.

I did it after the truck had been sitting all night

The battery saver relay is in the instrument cluster and not serviceable, the accessory delay relay is in the fuse block and is serviceable. The fuse in an 05 just goes right to the cluster. If you think that is your draw, let the truck go to sleep with the amp meter on it and see if the draw goes away when you unplug the cluster. The max allowable draw is 50 milliamps on the whole truck.

When you were hooking up the amp meter did you completely disconnect the power to the truck? If you did then you need to let it go to sleep again.
