Speedometer, tachometer, etc. gauges in cluster started to go off...
Dodge Caravan 1997 worked well, just inspected in May. Occasionally speedometer, tachometer, oil/gas gauge and temperature started to go off and than on again without clear reason. After 2 weeks, everything is off, but car runs ok. Three professional services checked (cost a lot), no reason found. Instrument cluster replaced by new, did not help. Bus seem to be ok also. Any hints appreciated!!!
