Hi all, new to BMW ownership and this forum, but hope that this car is as interesting as this forum as i think its really good.

My question:
1998 520i, 2 litre 90k on the clock most history.

on the heater control panel, the small rocker switch that controls the blower fan is working in reverse, when you push the left hand side (-) it increases the fan speed and so when pushing the right hand side (+) it decreases the fan speed, no other problem at all. i have googled up and found nothing, I was thinking could it be the control panel needs to come out and is the rocker switch on the wrong way round, not sure if the switch is part of the panel or a separate bit that may have been put on the wrong way round

Many thanks for any help and advise given
