Hello everyone, I have a '98 Dodge Ram 1500 with the 5.9 engine in which the speedometer, odometer, and radio don't work for 95% of the time and the other 5% of the time it randomly works. I was wanting some ideas as to what would cause this other then a loose wire connection.

Thank you for any replys

 

The first thing I would look at is the ground, I don't know if they share one or mot. Ive seen a bad ground at the battery do random things and still start the vehicle.

 

Also Check the connection at the PCM... Give it the wiggle test and see if it has a good or bad connection..
