all 4 windows do not work on 1998 Buick Regal

One window stopped working that the next and finally all stopped working

Asked by for the 1998 Buick Regal
Can you here any noise inside the door when you try and operate the windows? It could be that one or more of your window regulators has failed. Each door will need to be checked to see exactly what the fault is with that window. You may have a different issue with each door causing the windows not to work.
