Re: Air Con Pusher fan Not Turning

Wpoll...What a clear concise explanation of what should do what !!!
It's been as clear as mud up to now !
I did watch a youtube vid of a guy activating his auxillary fan on an E46. When he clicked on the E-Blower ON button he got a small window up which allowed him to input a percentage of what he wanted to run the fan at. Obviously not with the E53 !!
When I select E-Blower ON...I get nothing. but this may not mean the fan is buggered....it may be that the square wave signal is absent.
Thats why I need to prove this before I buy a new fan. signal...or fan.
There is 12v at the fan so the power is there but I still don't know if the sq. wave signal is there to ramp it up.
I was hoping this may be monitored in INPA.
I'm presently looking for a small hand held oscilloscope on Fleabay to try and take this investigation further.
Finally, yes, the aircon does work when the car is moving forward but I dare not leave it running when in standing traffic because thats where this whole saga began last year....it just didn't stop blowing cold....because there was no cooling of the system, the pressure build up ws so great it blew the compressor and I dont want that to happen again...I would sooner get the fan ramping up and down.
Thanks for your reply though.
