F30 328xi RADIATOR FAN NOT WORKING...HAD FAN REPLACED
Im having an issue with my F30. The radiator fan isnt spinning how it should. There are times it spin but most of the times it doesnt spin. I ended up buying a fan and we are having the same issue. When we checked the fan harness the live and grounds gives a reading however the small activation/signal wire is reading up and down (mostly 0.2 and and rarely goes up to 1.2 then back down). We checked another 328 in the shop and its activation/signal wire reading is constant (1.2) so we are thinking there is a problem with wherever this wire comes from. It was traced to the firewall leading to the passenger foot area. Anyone knows what sends signal through that wire? Any suggestions?

Sorry to hear... it seems the HVAC fan is an issue with many generations of BMWs. I had to replace the blower on my E82 twice.
I wonder if it's the wires or the final stage resistor? Similar post: http://www.m3post.com/forums/showthread.php?t=1004338 |
