Toyota Sienna 2009 Sliding Door Question: Please advise.

What is your question?

The cable on my Sienna for the electric sliding door snapped and I was quoted approx. $1200 to fix it. It is not part of the 04-07 recall for this problem. The door can still be opened manually however. Is it a problem to simply open manually as long as the cable is cut? Does it lead to other problems with the electrical components if we decided to get it fixed down the road? Thank you.
