I need some help with the windows and door lock system. Seems that as I drive the car the windows will go up by themselves. Once they do, you can not put them back down. After several miles and constantly pushing the down window button the windows might go down. What could it be?

Could maybe the "Loom of Doom" at the left hand side boot wiring?

Hi and welcome from Warwickshire in the UK.

Is it both windows and is it simultaneously?
That is an odd fault if it is. Going to be where connection for both windows is common if it is, so, I would suspect wiring loom as, if I recall, the switches are separate ones either side the transmission tunnel.
You mentioned the door locking too. What’s the issue with that and is it related?
