Most of the window related rattles, in the conditions as you describes, be caused by worn out window mechanism parts (cables).

Can you replace cables only or will the whole regulator need replacing? it literally sounds like pebbles or rocks when going up and down

One or more of the cables is probably disconnected from its mounting point on the regulator and hitting the window as it goes down. The regulator is an integrated unit. It may be possible to repair, but you'll probably need to remove it to examine it.

Well, I took apart the whole door panel/speaker assembly to find... nothing? I was feeling along the rails that hold the cable and did not feel any part frayed. I do hear the sound in the area towards the front of the car in the door assembly just cant pin point it out? Do you think I need new window regulators? Or new cables? I looked around and it seemed like a PITA to replace(how do you even get those out to examine) or even diagnose the cables.. Any thoughts people? ... Sounds like pebbles but I can see hwo it could be a frayed cable sliding up and down sound..

A new window regulator should help you out, instructions are on the board, please use the search function.

I don't think your cable will be frayed, and you cannot replace the cable without replacing the regulator.

I think that it will either a) have become dislodged from its mounting points at the top of the regulator, where it's secured by a plastic grommet that can break or b)will be tangled on the spool in the motor assembly. These are the two most common failures. The noise you hear isn't a frayed cable, just the cable itself bouncing off the lower window edge, which will make a clacking and grinding noise.

To see either of these you need to remove the regulator. For a), you may be able to repair or re-set the grommet but you then run the risk of it breaking again. For B), get a new regulator.
