You were moving the video too fast. Can't you tell us in words what is happening?

sure ,first the driver side window goes down with no problem ,when it's fully down i pressed the passenger side window switch as i was pushing the switch down the passenger window goes down and the driver side window goes up simultaneously (without me pushing the driver side switch) ,and you can see in the video the instrument cluster lights like a Christmas tree too when both switch are pressed at the same time
P.S.: i recently replaced the window switch so it's not the problem
Hope this clarifies the video and thank you for the reply

It's a 2000 ML320
the BAS ESP , OIL, and COOLANT lights come on and the rpm needle goes up and down
if I restart the car everything goes back to normal and all lights off .
Oh and the lights keep flickering while the windows are moving ,once the windows stop only the BAS ESP stays on and the rpm needle settle to normal position .

Everything in the car works perfectly until I press the window switches ,but if i pressed a single switch i.e.: the driver side, the car behaves normally .

On top of relays 17-18-19 mark what number it is. Remove relay 17 and use as tester. Remove relay 18 and replace with 17 and see if the problem still exists. Do the same for relay 19.

Then it would seem that there is a wiring problem or you have a faulty fuse box.

Remove the window switch and look for any wire/s that do not look like they belong there.

If not, then pull up the fuse/relay module out of the fuse box and inspect all the many wires in there for similar wires that do not belong there.

Remove both covers to the fuse box and then remove the 3 screws and pull it up. Inspect everything in there.
