2002 Dodge Ram engine light

I've talked with a car professional about an issue with the fan relay switch before. He even told me that it could cost over a hundred dollars to fix. Instead, he suggested to check the radiator/condensor fan fuses. If one or both are blown, replace them. Since they are cheap, I'd recommend changing them anyhow and seeing if that solves the problem. He explained this to me as: "If there is a lot of dust or ice build up on the fan, starting your truck will try to force it to move, potentially blowing the fuses." Good luck, let me know if this works out for you.
