Blower Motor not working (no voltage at terminal )after replacing water pump

Hisho335i · 07-14-2013, 09:15 AM

I have a 335i 2007 E90 and the inside blower is not working, with a multimeter there is no voltage coming to the motor or resistor (tried all setting high) checked all fuses. still no voltage coming on the Motor/resistor . Climate control panel all green lights and it functions normal . That happened after changing water pump/thermostat. Also I get an external positive line attached directly to the positive terminal at the resistor , the blower works.
Either the climate control panel is not sending any signal or Junction Box. Is there any relays may go bad ?
any ideas
