2001 Sebring LXI Power Window Problems

I need help! A couple of days ago, none of my power windows would go down. I finally got the left rear window to go down and then all of my windows seemed to work just fine. However, the next day, none of my power windows worked. I am in the process of trading my car in and would like to get this issue resolved before trading it in. I need suggestions on what might need to be repaired and what the potential cost might be for each repair. My husband is an electrician and has checked fuses, circuit breakers and taken the inside panel on my driver's side door off to check for broken wires. We have no clue. Any suggestions would be GREATLY appreciated!!!:banghead:
