Hi
when i turn my ignition on the aux fan runs at high speed.
The AC compressor does not engage.

I never had a working fan since i owned the x5.
Got one from a working x5 with AC working great.
The engine temp is ok as it is just under normal.
Is there any way to test for the problem.

I have impa and pa soft.
I can remember checking codes for air suspension and seeing
a hvac error.

Thank you

Dave king
