public float speed = 3f;
public float resetTimer = 1f;
public float maxRot = 0f;
Vector3 direction = Vector3.forward;

public void Start()
{

}

public void Update()
{
    float timer = Random.Range(0, 3000);
Vector3 drift = transform.position;

    drift += direction * speed * Time.deltaTime;

    transform.position = drift;

    transform.Rotate(maxRot, 0, 0);

    if (timer > 0)
    {
        timer -= Time.deltaTime;

    }
    else
    {
        Debug.Log("turn");

        timer = resetTimer;

        if (direction == Vector3.forward)
        {

            direction = Vector3.back;

        }
        else
        {

            direction = Vector3.forward;

        }

    }
}

}

You got the problem backwards.

while (timer>0)
transform.Rotate(maxRot, 0, 0);
timer–;

This will turn for timer duration of time.

I would also recommend using Time.deltatime instead so your turn isnt frame dependnt.
