Hi, newbie here. Just picked up a 2005 530i and changed all the fluids, filters and brakes. Today we got lots of rain and on my way to work I couldn't get the manual mode for the wipers to work, just the automatic feature. Is my WIPER SWITCH bad or something else? I was going to order a used one on ebay. Also, is there a thread for the change of the
WIPER SWITCH? I tried to search but couldn't find any.

Thank you for all the help.
