All my windows stopped working. I figure its the master switch. Before I purchase a replacement switch I want to verify that it's the problem. It's cold out and I don't have access to a garage, so I planned on figuring out problem in spring. I just so happened to be flashing my ECU, and noticed that the drivers side window switch was lit but no others. I give it a shot , the drivers window works!!!??? The other unlit switches are still non-functional. I disconnect the flash block and green connectors and the window stops working???

Is my master switch ok? Why would one window work while in flash mode and stop working under normal condtion? Does anyone have an idea of what my problem could be?

Many and i mean many thanks in advance for assistance!
