Can a bad gauge cluster cause other problems?

I had thought about replacing it because the odometer and tripmeter do not work, probably gears could be replaced.
I'd wondered if maybe it could cause problems with my windows, they are done.
The oil gauge seems "sometimes", sometimes it does, sometimes it doesn't. I don't know if I can rely on the alternator gauge though it does not differ by great amounts.
I do not know what all problems an instrument panel could cause electrically, not much of an idea.
The car does start, it runs; sometimes more smoothly than others, it could be just the age and nature of the car.
The check engine light stays on, though there are many causes for that, but the car runs, runs well enough, so I don't trouble myself.
