Rear doors will not open using the inside door handles

[Canon2441]

I’m hoping someone can help with this issue I’m currently experiencing. Both of my rear doors will not open using the inside door handles.
Two weeks ago my rear passenger side window regulator went bad and I had it replaced. Everything was working fine until last Saturday when I took my family to a birthday party.
As they tried to exit the car, neither of the rear doors inside handles would open the doors. I had to use the outside handles to open the rear doors.
Both of the rear doors inside handles seem to have no resistance when you pull them. Could both of them have gone bad at the same time? Both rear windows work fine.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<img src=" /><o:p></o:p>
