How can I test the two auxiliary fans on the radiator I've noticed my engine bay has been getting hotter than normal car does not over heat and I've been through the entire coolant system like a million times looked at the upper most auxiliary fan and noticed where the blue wire is a little black where it goes in to the back of the fan and the plastic part looks to be melted so I'm thinking it fried just want to ensure any help would be appreciated I also checked the FAQ couldn't find anything on the subject about testing
