I have a similar issue with my 08 RTX
the other morning i noticed the odometer section was frozen and dim
i was unable to select trip modes, etc
everything else is working fine, but odometer is like frozen
I have a new braille battery that i put in a few months ago
yesterday when i noticed this, i pulled the negative cable off, and put it back on
turned the key, and wallaha... display is bright as usual and odometer changed too
on the way home from work, put key in and turn on, and noticed same issue again, dim and frozen, but the display is there, not garbled up or anything
hit the trip button, nothing moves, all other lights in dash function, etc...
when i got home i before shutting off, i hit trip button again, nothing on the display changed since it was "frozen", turned off engine/key, turned key on: same issue, turned key on again, and display came back, showed different trip setting, and went dim/frozen again in 3 seconds
not sure what is causing this and why all of a sudden it happened
i have 22k on it
when it became bright again, the "frozen" odometer reading did change, so did the trip mileage, and i was able to hit the trip button to get oil information when it worked this morning
anyone else have this?
bulbs in the dash all seem good too, so does everything else
