Walls Walking code problem

Hi guys,

I'm working on a walls walking code. What I'm trying to reach is to have two raycasts one in front of the player(looking down) and one behind the player looking down.

Here is my code

 var rayDown: Ray;
     var hitDown: RaycastHit;
     var FrontPosition : Vector3;
     
     FrontPosition = Vector3( transform.position.x, transform.position.y, transform.position.z + collider.bounds.extents.z);
     
     rayDown = Ray( ((FrontPosition)), -myNormal);
     
     var rayDown1: Ray;
     var hitDown1: RaycastHit;
     var BackPosition : Vector3;
     
     BackPosition = Vector3( transform.position.x, transform.position.y, transform.position.z - collider.bounds.extents.z);
     
     rayDown1 = Ray( ((BackPosition)), -myNormal);
         
     if ( Physics.Raycast(rayDown, hitDown, SnapeRange) &&  Physics.Raycast(rayDown1, hitDown1, SnapeRange) )
     { 
        Debug.DrawLine (FrontPosition, hitDown.point, Color.green, 30.0);
        Debug.DrawLine (BackPosition, hitDown1.point, Color.black, 30.0);
        isGrounded = ((hit.distance + hit1.distance)/2) <= distGround + GroundRange;
        surfaceNormal = ((hit.normal + hit1.normal)/2);
        print(hitDown.collider.gameObject.name);
     }
     else
     {
         //isGrounded = false;
         surfaceNormal = Vector3.up; 
         print("sdasdasdasdadada");
     }

this code works only when I'm moving in the right direction. However when I rotate the for example to the right (of 90) the raycasts became left and right.

I don't understand why any ideas?

Thank you.
