Hi, trying to fix my gauge problems on my 98 blazer, oil pressure and amp work -temp and fuel don't. I went and replaced the cluster gauge with a 99 that had the tach option. Same thing with the ones that work and the ones that don't but now the odometer and PRNDL won't light up. They light up with the key on accessory but with ignition on they turn off. Do you have to replace anything else when you change a cluster gauge?
Also, if the two gauges described work and the sending units work for the temp and fuel where could I look to try and get those two started.
Thanks in advance to all responders!
