...There are 2 Rheostats. The one for the Gauges is just under the 'lip' of the dash, over the drivers' left knee. The second is obvious, it's on the dash over the center console, this controls the console lighting.
The rheostat may be 'burned-out'. Test by jumping both wires, lights should come on Bright. Simple...Some models, the Ignition Key must 'ON/RUN' for the Lighting to Work!
Problems can also be caused by:
Poor Grounds.
Blown fuses, bad contacts.
Burned-out bulbs.
Loose/Burned/Melted wire connections.
Bad switches/Burned Contacts. Most circuits carry a High Amperage, they get Very Hot!
You have your work cut out for you!
Welcome to Our World of Pantera Ownership and 'Fix-ation'!
Go to panteraplace.com 'technical' and find wiring diagrams, that may or may-not coincide with your model Pantera, but can be close enough to take some of the 'guess work' out of your search. You Can NOT Depend on the Wire 'Color'! It's different from Model to Model, Year to Year.
Good-Luck!
P.S. The gauge lighting has always been DIM, to begin with.
