I have a 2004 530d I am hoping that someone can help me with my air con issues, it doesn't blow cold at all! I have searched google for answers and have checked the following:
The I-Drive and its on cold
The air-con system has been drained and re-gassed and they told me it held the charge really well.
When I press the AC button I can hear a tick which (i assume) means the condenser is engaging.
The cabin blower fans seem to speed up, as if they are trying to blow harder (gigidy)
The fan on the radiator doesn't turn on ever, even if the car has been run hard, or left standing at idle for ten minutes.
I monitored the coolant temp through the secret menu. On my drive home (18 miles) it maxed out at 83c after ten minutes at 70 an over, then when I hit congestion averaging 45/50 mph it stayed around 74c. I left it running at idle for ten mins and it got up to 91c and the fan still didn't turn on.
So, Can anyone please help me as to what to try next?
I have a test cable on order, so I will use that to test that the rad fan actually works, but would a faulty fan stop the air-con from working? or am I looking at another issue like a temp sensor?
