how to replace the winshield wiper motor on a 1995 bmw m3

My labor guide says it takes 1.7 hours to replace but I would look at the fuses, and test the switch and power to the motor first. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
