Title: Engine Fans start immediately Mks
Post by: Matt_Sommers on June 10, 2021, 03:40:08 PM
Hello, im not sure if this is normal for these cars or not, but in this slightly warmer weather we've been having I noticed that when I remote start the car the fans turn on after less than 15 seconds. Is this normal? Or has some switch failed/starting to fail? Thank you for your help!

Is the AC on? If yes, then the fans are supposed to be running.

Same here, both of my electric fans kick on when I remote start my MKS with the A/C on. It makes quite a roar with both of them spinning away. As soon as I get in and switch over to key, they calm down. I always figured it was a safety thing to prevent an overly hot motor when on remote start.

I didn't know that, I always have my a/c on so that would explain it. Thank you!
