#1

2007 Aspen Limited, 5.7 Hemi “No Bus”
Had previous issue several times with water entering passenger floor mat area when the sunroof drain hose clogged (located inside passenger side windshield post). Thought maybe this had contributed to problems now. Began with A/C only working intermitently. But now won’t start. Battery power OK, and have Power to Elect Control Box. Lights on dash flash and “no bus” appears.

A No Bus message usually means the dash/instrument cluster isn’t communicating with the other computers/modules in the vehicle.

A poor electrical connection at the back of the instrument cluster can cause this.
