[HELP] 2001 Blazer 4.3 Cluster Problems - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Camacorn · 09-10-2015, 07:29 PM

I just recently picked up a really clean 2001 Blazer 4.3 4x4, doesn't leak a drop of ANYTHING, and is clean inside, and out. Paid just $300.00!

However, the cluster is out of wack, while the Blazer is running, EVERY light on the Cluster is illuminated, and some flick on or off randomly. Every gauge except the Gas, and RPM work as well.

Can anybody help me diagnose this issue?

I took a little video of how the cluster reacts while running, and while starting. Sorry about the music, my other half was jamming out haha.

It also decided to work semi-normally for the first time since I've owned it. The lights all went out, and the tachometer and temp gauges worked.
