1994 Dodge Caravan, 3.0 V6, auto trans., cluster contains tachometer. Many months ago the gauges and speedometer would occasionally go dead for a second or two then come back to life as I drove. Over time this problem got worse (more frequent). I cleaned the body at every ground connection I could find, no help. Recently the entire cluster died for good. Only a red “check gauges” light. Although during start up the usual air bag, and other idiot lights do all light as expected. All fuses are good. So I bought another cluster at a junk yard. Still dead. All connectors look ok with no broken wires.
