Sliding door question (2 part question)

I have a 99 Windstar with dual electric sliding doors. The drivers side door apparently the motor went bad or the cable came loose. I need to either engage the wire back to the motor or replace the motor. Here are my questions.

1- What is the name of that motor that opens & closes the door automatically?

2- How do I access that in order to replace it of fix it?

If I dont know the name, I can not locate it on ebay or online stores.

Thanks in advance

Google "OEM Ford Parts" and look through the on line catalogs. They have pictures and part numbers. Look under the Replacement Parts section. If you don't see it most of them have an 800 number you can call. Plus its cheaper then the local dealer.
