BUICK LIMITED DOOR PROBLEM

2003 Buick Limited • 120,000 miles

There is no power to operate the back doors windows and locks not from main driver switch or from the individual door switch. When I open any of back door courtesy light does not come on but when I open the front door this lights come on properly.I change the main power switch with a used one but it act the same I checked fuses found them good. What other reasons may cause this?
thank for any help. Ami
