Weird Electrical Problem with Blower Motor

Hope you guys can help me out on this one.

My 2010 Seat Exeo blower motor is not functioning properly. It is blowing with like 30% of the power. BUT, when the windscreen washer motor is turned on the blower motor starts working with 100% of power for like 20 seconds and then goes back to 30%. Why would that be?

Thank you!
