New trick. Car usually will have cooling fans running when I pull into my garage, so I am in the habit of letting them run for a minute or so before I switch off. Usually, I can hear the fan begin to slow down which tells me its ok to turn off the motor. Last few days, temps are cool now in the 60's and normal city driving, when I now pull into garage, the fan kicks into hi gear and runs for a few minutes with no slowing down. So, I switch off motor while fans on HI and now the fan keeps running after the motor is off. This has never happened before where the fans run after the motor is off. All gauges show normal.. no CEL... I suspect a thermostat somewhere,.. any thoughts?
