when I bought my 99 gmc sierra the cluster flashed now and then, when I pushed on it then it'd light back up. now the gear selection PRNDD21 and the odometer don't light at all!


what to do?

 

An easy thing to check is to pop the surrounding plasic off and take out the little screws holding the cluster in and pull it out. Once it's out there's a harness plugged on the back. Make sure it's plugged in and maybe even turn the key to run and wiggle the wires a little to see if the lights flicker or whatever. This is super simple and should take maybe 3-4 minutes to do.

 

tried that, didn't help

 

Is it JUST the cluster? I had something similar happen to me, but it was the gear indicater/milage, fuel guage, temp guage, and somehow cruise control and the A/C blower motor did not work either. It turns out, after tracing a million wires and relays, that a plug on the steering colomn was loose but not completely disconnected. Sorry, this didn't help much, but I would say go through and push on all of your connectors before you begin tracing wires. Good Luck
