Very first quetion is "do ya" have a service manual. You can download one free from MyMopar, and several of those over there came from the guys here at FABO

I would at this point plan on yanking the cluster out. You likely have PC board issues, most of which are fixable. If you "get into" that there are earlier posts on this board we can help you find

"Some of" what to look for:

Poor PC board ground.........add a separate ground pigtail

Poor instrument regulator socket connections........solder jumper across from IVR contacts to board traces

Poor cluster connector pins to PC board......solder/ repair pins to pc board traces

Poor gauge stud connections to PC board.......loosen / retighten stud nuts, or replace "fake" nuts

Corroded / oxidized PC board traces at lamp sockets. Poor springs / corrosion in sockets.

If both gauges are acting up, a bad instrument regulator / limiter.
