A general watchpoint are the connectors to and from because they are very exposed to water ingress whilst driving leading to corrosion, and the high amperage the fan + resistor uses leads to a non-op fan when least expected, mine got so hot it melted the insulation because it's a 20 or even 30 amp ? fuse which in my opinion was too high for the cable size MMC used
