My car dont move

My car dont move and have rigidbody 1500 and this script

#pragma strict
var wheelFL : WheelCollider;
var wheelFR : WheelCollider;
var wheelRL : WheelCollider;
var wheelRR : WheelCollider;
var maxTorque : float = 50;
var Speed = 10;
function Start () {
 
}
 
function Update ()
{
wheelFR.motorTorque * Input.GetAxis ("Vertical") * Speed;
wheelFL.motorTorque * Input.GetAxis ("Vertical") * Speed;
 
}

I’m having the same problem, everything was working fine in 2019.3 but not 2019.4
