Hi PetrolDave, Thanks for your reply, please note 4 windows & 4 doors used to open/close on long press open/close fob buttons all the time in 7½ years I've had the car from new. Hopefully I've followed your instructions correctly, here's what I did: 1 Long pressed fob open button (all 4 doors unlocked - all 4 windows remained closed - as per my post 2 Opened driver's door, opened all 4 windows on driver's window controls, closed driver's door and long pressed fob open button (to reset it?) 3 Closed all 4 windows on driver's window controls, closed driver's door, long pressed close button (to reset it?) & all 4 doors locked 4 Waited 30 secs, then long pressed fob open button, all 4 doors unlocked, BUT all 4 windows still remained closed Thanks for your help & instructions, I'm sorry I'm late in replying to you. Should you reply, please note I won't be able to respond until Monday
