This is a common problem with most all BMW's it entails the removal of the top of the dash board to remove and replace the blower motor and its components such as the blower motor resistor and the final stage relay, it is so labor intense that anyone working on this job would only do it with the agreement of changing out all three parts...blower motor, final stage relay, and the blower motor resistor, this is definately a very difficult job for any DIYer and can cause more harm then good doing so, I advise using the dealer for this repair or a very reputable European Repair Facility that has ASE Certified BMW Technicians onboard, you may want to get a few second opinions on this however so you can prepare yourself for the job and its expense, unfortunately there is no easy way out with this repair, and it is not a simple fuse replacement.
Good luck to you, sorry I had to be the bearer of this news but when you speak to BMW in the a/m they will pretty much elude to what i am telling you.

My bmw 318 is blower fan not working


Blown Fuse
  • Usually the first thing to inspect when the blower fan stops working is the fuses to see if any are blown. Locate the 10A cluster fuse or the 25A HVAC fuse in your car manual, and examine them to determine if they need replacing. The car owner's manual will tell you where to find the fuses that are connected to the heat and/or air conditioning. On the interior fuse panel of the car, a 30 amp fuse is labeled "Heater" or "HVAC."

Bad Blower MotorIf the fan only works on setting number 3 or 4, or just on the highest setting, it is most likely that your blower motor is failing and is about to die. Use a voltmeter to test the amount of voltage at the blower motor connector with your ignition on and AC running. If it reads 12V, the motor needs replacing.Automatic Climate Control SystemAnother thing that causes the blower fan to malfunction is the Automatic Climate Control System (ACCS). If the ACCS's settings are off, it may cause the fan to stop working. If it is the climate control on the car, typically it is a bad thermostat or electrical circuit that is the culprit.
hope this helps, James Booth

Hi My heater and air con has stopped blowing


Hi!!

Let's start with the basics, check blower motor and AC fuses and relays, also take a visual check to the wiring going to the Blower Motor (Firewall, passenger side). Look for broken wires and loose electrical terminals.

Let me know how it went.

Good Luck!!!

The blower is not the problem
The problem is a faulty final stage resitor located
on the passenger side under the dash.
Very common - easy to replace.
