Default Fan running fast
Hello all
i have a ‘15 JL so have the 3.6. Recently the fan has started to run really fast. It’s in the 40’s and 50’s outside, not really hot yet. It just happens occasionally and doesn’t seem to be overheating. Is there a fan relay or control I need to look at? Anyone else had this happen? Has 106000 miles on it with no problems so far. Thanks

Are you running your defrost? Defrost engages the AC system which turns the fan on high speed.
