What causes this kind of buildup in a relay harness? It's like tobacco / syrup. This is the fan high relay on the driver's fender. I replaced the high and low relays last year and recently couldn't get the high to work without mashing the connection together REALLY hard. I finally picked up some CNC contact cleaner and sprayed the harness and relay itself and the connection is good now and works just softly connecting the relay to harness. Pic shows what I'm talking about. Looks like a 95 yr old chain smoker coughed up a lung.
