electric window drivers side

[kavvie]

since i bought the car almost new (avensis diesel overmount 2014) the window switch  has been acting up.as in it will work today but not tomorrow.if i bang the side of the door gently it then works.i was talking to a guy a few years ago and he said it wasnt the switch but something in the logic? anyone any ideas.? it might work ok for a month but then acts up regularly.(as in last few weeks!!)

I think your car may be still be under warranty, if within 5 years or 100,000 miles. But, it depends where you are located as this applies to the UK at least.
