No AC or any air on 2007 328i

I am faced with a ventilation problem. All lights on.... no AC, no defrost, nothin.. After doing some reading I decided that I should replace the final stage resistor on my 328 as this was apparently a common problem.... nope, all lights on, no air blowing at all.... Do i need to replace the blower itself... anyone else have this problem, or am I missing something?

You did check the fuse, right?
Take a small ballpein hammer, or a piece of hard wood, and tap on the blower motor housing when the switch is in the run position. Does the blower activate?
Do you have a test light, or a multimeter (a volt ohm meter)?

stick you head in the dash/under the hood. have someone turn the a/c on and off. keep it on low and see if it kicks on or not. follow up

Tried tapping blower housing and did check the fuses related to the ventilation system.... Felt a tiny bit of AC while playing with controls switching from AC to defrost to see if anything would happen so I am somewhat comfortable that AC does work. I do have a voltmeter, but not comfortable enough to start testing all the pins, plus wouldn't know where to start? Any guidance would help! Thanks for responding.

By the way, tapped the motor with hammer....not a beep, you can hear all controls going from defrost to AC, but no fan noise at all.

Your symptoms indicate a problem with the blower motor. It it were the resistor circuit (which controls speed) it would work on high speed only as that is the 'fail safe'. There is a possibility that the switch is bad but I don't think so.
You'll need to check for voltage at the blower motor after removing the connector. Get a wiring diagram to identify the wire colors which you need to check. It's highly unlikely you have a two pin connector, probably five or more pins and you'll need to know which is which.
An easy check is to find a friend with an identical car and plug his blower into your wiring harness. Whatever, be careful when you test, you don't want to accidently send 12V unfused somewhere it isn't supposed to go. This is an easy check but you still have to know what you are doing.

Hey DSX, thanks for all advice... Got a new blower unit and used a DIY.... managed to fix it.... Fan was shot..... $350 parts for resistor and new blower, no labour, except a little love!!!!! starting to like the car again. Cheers!

Great, yeah you spent some money, but a lot less than having someone else do it for you, and you have the satisfaction of knowing you did it!
Stay cool!

Looking for the part number for the FSR...DIY photo/instructions.
Can you help a brother out????
