Gauge illumination issue

[tenga]

So A few days ago I noticed that the interior blinker light for the right turn signal went out. The actual turn signal works just fine. Now last night when I was driving home I noticed that the speedometer (which is one the right side of the dash as well) wasn't illuminating. The two don't use the same bulb, so I can't imagine them both burning out at the same time. The left interior blinker, and the tachometer light up just fine though. I'm stumped.
Will take pictures whenever, if needed.

my ranger did this, bulbs were just burned out. just pull the cluster out and replace them all at once save yourself alot of trouble in the long run

Well, I was in the process of getting the cluster out and I accidentally hit the turn signal. And now it works. Short in the wiring or something?
