<![CDATA[AC blower problem]]>This is my first time posting. I have a 2000 740i that has several problems. It is actual my wife's car and she loves it. The A/C motor is growling and shuts off intermittently. I have preview the post as to how to remove and test the motor, but i would like to find out why the A/C system come off and on. Could it be that the fan motor is so bad that it is getting stuck and then restarting?

I would appreciate any help as taking the dash off is no easy job and I would like to do it right the first time. I replaced the evaporator coil a few years back and had to take out almost the entire dash to get to it.

half the job of the heater core. Jeff did a write-up on here awhile ago.

Not a hard job just tedious and time consuming. Be patient and take your time.
a 2nd pair of hand will make the job much more painless.
Expect to break a few clips and plan for it.

replaced this with my son in about 3 hours.

I am not sure how similar it is but I have replaced a blower motor on an e32, it would run and could hear it changing speed as you adjust the speed selector but was always too slow and sounded bad.  I can look for some pictures if you would like.  I replaced it from under the hood by moving the coolant reservoir and the covers.  It is tight but better than removing the entire dash to access the hvac box.

A quick search makes it appear to be a common issue on the E38 with a new blower motor resistor being the fix

Im sure you are aware of E38.org but if not it appears to be an immense vault of great info (where I found the link above)

http://www.e38.org/

Probably a worthless post on my part since it sounds like you know what you are dealing with, but just attempting to be helpful
