Hi everyone. I just joined the site after finding it while researching a problem with the instrument cluster on my 2004 Tahoe. Around 50K miles the guages started acting funny - which I understand is a fairly common issue. I pulled the cluster out and replaced all 6 stepper motors and in the process realized I've got 4 bulbs that are burned out. Rather than buy an entirely new cluster, I'm tring to identify the stock bulbs and find somewhere I can purchase to solder in myself. Love the site, really appreciate any help anyone can provide. Thanks!
