I have a 2003 350z and over the last few months I've been having an intermittent issue with the heater blower. When the car is cold the blower will not run, occasionally when hot it will, I took the fan out from under the dash, and let an electronics wizard at work have a look, it turns out it is a brushless motor and requires a pulse to make the fan spin, we emulated a slow pulse and managed to make the fan move! We are guessing that something on the control circuit is goosed and not pulsing to operate the fan, I rung my local Nissan garage And was quoted £500 for a new fan, but not being 100% that's there could be an other fault causing this issue I'm reluctant to part with that kind of cash! I was wondering if any one had any experience of this issue? If so how it was fixed? There are second hand fans on eBay but not the correct one for my 350. The bloke at Nissan said I need one for a 2004-2007 model with a 3 pin plug on it! Any help would be much appreciated!
