My 2014 vibrates and pretty much shakes the entire car at idle when the radiator fans come on and doesn't stop until they go off . What can I look at?

 

The fan probably has a bad bearing in it

 

how can I check?

 

Bad bearing or a piece missing from a fan blade.

 

And there is nothing else to check before going to the fan?

 

I would see how well they turned by hand with the car off. I would also see how well they spun while running. You may see it wobbling

 

I checked it while it was off and t seemed fine

I was trying to go the cheaper route before buying a new radiator fan I would imagine that it's not covered under warranty I watched it this evening go off and. On and it looks fine from what I can see with my eyes
