Hey all

my discovery sport 2017, for some unknown reason, every time I start my car my driver side, passenger window opens.
• I can’t or the passengers can’t close the window if the car headlight is on.....

If I set the car light to off, I or the passenger can open and close the window.

If I have my headlight on set to auto, turn on the headlamp, or start the car cause the light is set to auto my driver side passseger, window open.... this is conusing the crap out of me. Only thing I done is got my window tinted and wash the car...

please help

The only shared wiring I can see is an earth from the BCM. I don't have a list of earth locations unfortunately so I'm not sure where this is (there may be several on the doors). Obviously a code reader would be useful, to start with, to see if there are any error codes. The Autel AP200 is excellent for use with a smartphone. You really need to book it in to a good independent garage.

was planning to book it in with Range Rover on Monday, it just bugging me atm, that all 3 windows are fine but not this one grrrr
All I had exactly the same issue rear window winding down on my 2016 Discovery sport, when I turn on the lights .After reading all kinds of awnsers on forums all over the place and Landrover rip off.I took a chance on my master control switches in the driver door .I pick up a preowned 2019 set of switches for £34 and replaced the old one and it solved the problem.

Hello my 2019 Discovery just started doing this. Did you ever figure out why and how to fix this annoying problem?
