power lock module
 

I have a 2002 taurus wagon and am having trouble finding the power door lock module.
When I go to lock/unlock the doors only one door( left rear) works.
After checking all door lock actuators, I have come to the conclusion, that it must be the DLM.
The Haynes repair manual shows nothing about where this module is.
Does anyone have a picture or diagram of where this is located?

Thanks
