I have 2001 Dodge 3500 with Cummings engine, with just a little over 100K on it.
Now I have a gremlin in my instrument cluster, because each time some light is stuck, sometimes as many as 5 and the rpm also.
As big as the Internet is, I can't find something about computers or control module.
To make it more complicated, the fuel gauge is out too but that could be the sending unit. And last one is the oil gauge, that was in and out frekvently and now it works 100%.
It's weird, that everything was perfect for 100 000 miles and now so many things are causing problems.

 

Hmm, nobody has a same experience?
