It says replace combination meter. I was assuming that was different than cluster, but maybe they are one in the same. This is new to me so I am sorry for the confusion.
I’m actually gonna order the cluster tomorrow. I went tonight and checked every single fuse again. Even the ones in front of the battery. I could not get to the small box but I’m assuming that has nothing to do with it..
thank you for the help guys. Let’s see if I can fix it for him.
As mentioned in post #20 above, once you remove the old cluster I would strongly suggest you probe the power, ground, and IGN signal wires at the harness connector. This will rule out any power or wiring issue while you are waiting for the replacement cluster to arrive.
so last question. I took car to my friend who is a mechanic. also about a year ago the gas gauge started not working and showing fuel when empty. After interrogating my 18 year old he said it blanked out once a few weeks ago and came back on. My friend believes it to be the unified meter a/c amplifier? Does that sound right to try.
I am having a hard time recognizing a used one and where to buy. I have the cluster coming as a back up. any recomendations. This seems an easy try before undertaking cluster.
The Unified Meter & AC Amplifier serves two (2) main purposes. First, for the Unified Meter "portion," per the FSM, "Receives information required by the combination meter from various units via CAN communication line and transmits it to the combination meter with communication line." Items like vehicle speed, engine RPM, fuel/temp, as well as the MPG and other items in the center LCD screen (between the analog gauges) all receive their inputs from the amp. Second, the AC Amplifier "portion." That is self-explanatory.
That said, you stated that the original issue was that the cluster was completely dead as in nothing was lighting up and none of the gauges moved. If the amp was the issue, no data would be sent/ received to the cluster but the cluster should still turn ON. When given power, ground, and a IGN signal, the cluster should light up. Here is my Q60 test cluster:
In other words, the cluster should not be dependent on the amp to at least illuminate. Still, when it comes to electronics, anything is possible.
However, it will be a lot easier to swap out amps than clusters. If you are game, by all means feel free to pursue that option. If nothing else it will likely fix the incorrect fuel level (common issue for these cars lately). Just take note of the connectors when you unplug them as it is VERY easy to mix them up when plugging everything back together. The connectors for the amp are marked with yellow tape from the factory.

Well guys, thank you for all your help. I replaced the AC meter and that did not do it but he had a fuel problem before, so I just left it. I picked up a new used cluster, just got done, taking it apart with all your help, and it all works,.
I really appreciate everyone’s help so my son can have his car back at college…
The last thing after I took it for a long ride is that the airbag is blinking on the dash, I guess that might be because maybe the last person who had the car crashed it in the airbag signal came out?
Is there a way to reset that or should I just undo the battery since I never did that yet
