ATTN: Expert Mechanics! Mercedes Benz C320 2002 Wiper Problem HELP!!!?

Hi,
Just got the lovely service call from the Mercedes Benz dealership. They want to charge me $790.00 for a new wiper motor!! PLUS $125 hour service fees!! My wipers are in the “parked” position on top of my windshield …. Is there anything I can do myself to fix this!! I am not paying 800 so my wipers stay down!! …

They work perfectly fine!! Just “parked” ontop of the windshield..

PLEASE HELP!!
thanks!
