Just try first a simple thing. Just disconnect the battery for a couple minutes then put it back and see if this "fixes" the issue..
Driver and passanger windows stuck and not rolling up/down
Out of the blue the driver and passanger windows got stuck open. I made a scan with the OBD2 and these codes poped up:
The weird thing is that both windows stopped working at the same time, so I guess it has nothing to do with the motor. I have already tried to close one of them from the passenger side but it did not work. The passenger windows in the rear are working fine.
I have also noticed something else: whenever I turn the keys to postition one (before ignition), it is expected to see all the pointers in the painel move, however the engine rotation and speedometer pointers do not rotate. Any ideas on what could have happened?

I know, right? Nothing was done on this car. The last problem I had was the famous negative battery cable, but this was over a year ago, the car was working fine until now. I think this problem is with a module connected to the BCM or something. I do not think it has to do with the motors pushing the windows. And as I mentioned, the pointers in the panel also stopped working at the same time.
Update 1:
The problem is intermittent - it comes and goes. A few days back the problem vanished and the car was completely normal, now it's back. I am guessing it has something to do with the negative cable I changed months back. The question is: why did it take so long to happen?
