Noticed the other night that the high beam indicator is out in my inst cluster.
I pulled the cluster out of the truck and pulled the bulb and socket out tested the bulb with a power probe and the bulb lights fine. so there goes my easy fix. I cant find a wiring diagram for the cluster and can not check the grid on the back of the cluster for power because i cant get to the grid withthe cluster pluged in. If anyone has a diagram or has dealt with this issue before ant tips would be appreciated. if i have my fog lights on and turn the high beam lights on the fog light indicator by the headlight switch goes out so i know its getting a signal to that point. The truck is the 01 in my sig.

 

Anyone?

 

I looked closer at the back of the cluster and can not see anything wrong with it or how anything could go wrong unless the circut board is somehow shorted or open circut for just the high beam indicator. With my luck and the history i have withthis truck it will most likly need a inst cluster.

 

Sounds like the next place to look is the multi-function switch. They are known to eventually fail due to dust/dirt etc.

Check the fuses on the fuse panel under the hood. There are 2, one for left headlamp and 1 for right headlamp. I think the high beam indicator is the "telltale" that one of the fuses is burnt out. This problem drove me crazy for monthes.

 

Truck have day time running lights by chance? if so the module may be fubar. I unplugged mine and crimped two of the wires together. Light works now. I will post a pic of the wires if needed.

 

Thanks for the replies i have been up north away from the computer. Ill go check things out with fuses etc and let you know what i find.

 

Found A Fuse For "cluster B" Was Bad Put In A New One And All Is Good.
Tks For The Help
