Clusters Are Fairly Easy To Remove On Some Makes / Models. I Don’t Know A Nissan Maxima From A Bale Of Hay.
I do know you’ll need a repair / shop manual that has the cluster removal / installation in it.
Also, don’t overlook the possibility that a poor / loose connection(s) is the culprit. I’d wiggle some wires around or plug and unplug some harnesses when I popped that cluster out.
You may not need any parts.
