Air Conditioning problem
2002 BMW X5 6 cyl Four Wheel Drive Automatic 52000 miles
----------------------------------------------------------------
AC CONTROL STILL LIGHTS UP BUT AIRCON IS NOT WORKING AT ALL, NO AIR IS COMING OUT ON VENT EITHER. 2MONTHS PRIOR TO THIS A/C IS ACTING UP, VENT BLOWS HARD THEN SOFT AND EVEN IF THE ENGINE IS TURNED OFF THE BLOWER STILL GOES ON AND YOU HAVE TO TURN BLOWER TO MAX THEN TURN IT DOWN, ONLY THEN WILL IT STOP. HELP AND ADVICE APPRECIATED!

The blower motor control unit known as the final stage will require replacement. It is a fairly high failure item and the part # is 64-11-8-385-549. It is accessed through the passenger foot well and removal of the side carpet trim is needed.
