2nd gen 5.7 all five windows not working

I need some help. All five of my windows, auto head lights, and auto lock while driving all started not working at the same time. All fuses and relays are good. I'm a mechanic and couldn't figure it out. I have had two shops look at it and they can't figure it out. These systems are not tied together according to wire diagram. I'm leaning towards a bad ECM. would appreciate any input before I pay Toyota $100 dollars an hour to figure it out!!!

 

It happened while you were driving? Try to pull the battery and wait 10 minutes then plug it back in, after that, go to each window and raise it up and down to see if it works. On my Lexus, i had the same issue after changing the battery, none of the windows work from the master switch, i had to manually roll the windows up and down at that corner then it worked. Seems like you might've already done this if you were a mechanic but just in case. That's weird.

 

I already tried that. The truck was sitting while I was out of town. My wife went to move it and it wouldn’t start. They jumped it to get it running. Tried to jump it again and it wouldn’t turn over. She thought that the battery needed to be replaced. She replaced battery and still didn’t turn over. She gave up and waited for me to get home. After all of that I have the issues I posted earlier.

 

Did you check the fuses by the drivers side knee kick panel?

 

When they jumped it, did they put the terminal on correctly? Also happened to a customer of mine, he got his battery replaced at Autozone and the terminals were hooked up reverse. That fried his fuselink and none of the electronics worked. Try that
