I pressed and held down all four window switches the other day when I put the dog in the car from the kennels.

I don't know if I've over-strained something by holding the driver's button down for 2 seconds too long, because there's a feint tapping noise now and the auto function has stopped.

Do I just try the 5 second reset trick or have I knackered something?

Just reset. Works for me every day...
