Anyone know why power windows would work intermittently??? Sometimes they go dwn and sometimes they dont.....sometimes theygoback up and sometimes they dont???? Fuse is good and tried a new switch assembly on driver door??? Any help here?

 

The pins in the connector can be bent slightly and will only work every so often or their continuity is terrible. Take a ohmz meter and take a schematic and test the pins to see if they work properly.
