So today my wife leaves for work and the 4WD and Brake lights on the dash are going off.

Had the vehicle taken to the dealership and just got a call back saying the cluster is bad.

They want $450 to fix it.

Is this a DIY project or am I stuck to the $450?

I called a local parts place and they said no matter what the vehicle has to go back into the garage for programming for a new cluster.

Are there any recalls on these clusters?

there are no recalls on clusters but check around an auto repair shop may be able to do them cheaper. there are several places that rebuild them so contact them they are onlline. any repair shop can reprogram them if it needs it.

After the shop returned the vehicle nothing was working on the cluster other than the turn signals and the check engine when you start it.

I called one of the rebuild places and they didn't think it was the ICP cluster. Thought it was something else, suggested ignition switch assembly.

Today, I took it apart, cleaned the ICP with 70% isopropyl alcohol. There were about four spots on the back circuit board that looked corroded.

I also swapped out the ignition switch assembly too.

I've not driven it around much yet today but so far it's all working again and have not seen one glitch yet. The primary issue was the 4WD and Anti-Lock Brake lights kept coming on.... All other gauges worked fine.

I'm sure this is a temporary fix... but time will only tell.

you never know sometimes the corrosion is the problem and it screws things up due to low voltage. hope it works for you.
