lost power to my windows and doors on my 2000 silhouette, the door buttons for the windows and doors do not operate niether does the quarter glass. But there is power to the locks when the van ingages into drive or park, just fustrating talking to people you have to open the doors all the time

HAVE YOU CHECKED FUSES OR THE LOCK OPTION ON THE SWITCH TO ELIMINATE PASSENGERS FROM USING BUTTONS???

Have checked all the fuses and all ok have even bought new controls for passanger and drivers side but that was not the problem the only other thig I might have to do is replace the BCM the only problem with that it is electronic and when you pay for it its yours no reunds and its a costly piece

DID YOU CHECK THE LOCK OPTION SWITCH??? HAVE YOU CHECKED FOR POWER TO THE SWITCHES?

yes I have checked for power and that is fine I can not locate any button that would lock out the windows or door locks there is not one on the master door lock nor any other control that would look like a power lock. and thanks for trying to help me with this problem its getting me fustrated
