Jim, The fan circut breakers are in the compartment behind the passenger. Remove the board covering the relay's and you will see two circut breakers side by side up against the back of the front wall. The one on the right is for the fans. You will see the brown/orange wire and a black/orange wire coming out of it. If your fans are clicking on and off the feel the breaker. It might be overheating and acting like a relay by opening and closing. Also look for any wires that look like they may have over heated. If you need a circut breaker, I sell them for $4.50.
