Crunsching window regulator sound, a few questions:

[haz]

Hi all.. I KNOW there are many threads on the topic of window reg fails.. (I did my searching) but I just have a few questions I couldn't see being answered, so please be gentle:

(I popped down my pass side window as usual yesterday, came half way down and stopped as it made a crunching / stone-rushing sound at the same time.
I stopped it and tried clicking the button to make it go up - but no go.
I manually pulled it up as it was raining.
I have not tried to click eiter up/down buttons after this).

- Do I need a completely new regulator?
- Can the cable be fixed if it is just snapped in two?
- Is it always a new window regulator that is needed or could it be different errors here?

I am asking since I can't just remove the doorpanel in the street I am parked and look for myself.. I need to have the remedy the time I am parked inside a place..

Thanks guys.. I am just fed up with stuffing $$$ into this car now..
