Team,
I’m having the same issue I have had for over a year and before I run it down to the local bmw specialist I wanted to ask if anyone knows if there is a specific combo or sensor/switch that turns on the cooling fan when the a/c is turned on? I know the computer looks for 7 or so different readings to control fan output.
I have 2003 2.5i, manual
-Ac blows hot air
- compressor is engaged and spinning.
- local shop evacuated/recharged and added dye
-Cooling fan comes on when temp needle is in middle of the temp gauge. Turns off, etc
-Fan does not come on when ac switch in cabin is turned on and compressor is engaged
-cooler sensors replaced
-replaced cooling fan with new bmw genuine fan
I did not replace the ac pressure sensor but not sure if there is an easy way to test it yet(tonight’s reading)
Thoughts?
