I have an 84 LX convertible.

I have been noticing that when I try to open any of the 3 passenger windows from the master control on the driver side door, they dont move. But if I reach over and touch switch for passenger window it moves, then the master control works that window again. Same with the 2 quarter backseat windows.

It's strange. Either it works or it doesn't. How can it be that the master control wont move the other 3 windows until I trigger those windows switches directly? Then the master switch will work all day. The next day, same issue

Could be a bad master switch, although I did swap it with a NOS switch a few years ago but I suppose it could be going bad. Anyone else seen this happen?
