93 Altima 3 powers windows out

I have a 93 altima with only the driver side window working. I tried installing a new master switch, but the same problem persists. When I play with the master switch the windows click, but they don't go up or down. I'm not sure if I need a new motor or regulator. I read on ebay that the module sometimes blows (which is a small black box where the window is plugged into). Any help would be appreciated.

I CHANGED THE MASTER SWITCH CONTROL WITH A NEW ONE,NOW BOTH DRIVER'S SIDE WINDOWS WORK ,BUT THE ONES IN THE PASSENGER SIDE DON'T WORK I HEAR A CLICK COMING OUT OF THE POWER AMP(LITTLE BLACK BOX).IF I CONNECT POWER DIRECTLY TO THE MOTOR (BLUE/BLACK CABLE AND BLUE RED/CABLE)THEY GO UP OR DOWN IF I REVERSE THE POWER LEADS ,THAT MEANS THEY ARE OK.I DON'T KNOW WHAT TO DO NEXT TO FIX THIS. :banghead:

I THINK I FOUND THE PROBLEM WITH THE POWER WINDOWS.IT WAS THE AMP" ASSY POWER WINDOW"(LITTLE BLACK BOX BEHIND THE DOOR PANEL).I TOOK THE ONE ON THE REAR DRIVER'S SIDE THAT WAS WORKING AND CONNECTED IN THE FRONT PASSENGER SIDE AND THE WINDOW GOES UP AND DOWN NOW.I'M GOING TO BUY THE OTHER TWO IN THE REAR. :biggrin:

Where did you get this part? I seem to be having the same problem, which started to occur after my audio amp broke. As I was running the new line back to my amp in the truck I turned the car on to notice only my driver side drivers window works. All other windows do not even budge after pressing any buttons. If you solved the problem, where can I pick up this master panel and those AMP boxes for the motor?

As I was getting out of my car today after driving to my mom's house I accidently pressed the "window lock" button and thought to myself: What if I accidently pressed this while running the wire. Sure enough, I had the "Window lock" button pressed down and all 3 of the windows work fine now. I suggest you check the same if you havn't done so already.
