Cluster Help (many trouble codes)

[Poobank]

Hey guys, I'm new here. Just bought a 2001 Yukon 2500 8.1L and needs a few fixes. I just replaced my instrument cluster because my fuel and PRNDL and temperature gauge didn't work and I have warning lights for security,battery , low fuel, abs and airbag. The new cluster didn't fix anything. Still having the same problem. I live in carrollton Georgia. Could anyone point me in a good direction whether its troubleshooting or a good mechanic? I'm at a loss right now. I checked all the fuses that I could. Fuse seo 2 was blown. It had been in a minor wreck on passenger front. Any info would be appreciated.
Thanks

I had a similar issue with my '99. ABS light was on, "Service 4wd" light came on when I turned the fan on, the heat control didn't work nor did the push button 4wd.

It ended up being the wiring harness that connects to the ignition switch. It was somehow doing erratic things with the power that feeds the systems.

Good luck.
