    Same problem, when I would turn on the A/C it started making a "straining" sound.. then 1 day later it quit completely... no air no fan...



    I took it to the Auto Bavaria in Hemet they looked at the fuses since I didn't have much time ... Nope not the fuses, so I'll have to leave it there tomorrow for further diagnostics... I'll let you know what they come up with..

    I recently had to replace my whole 1998 328i Convertible air controler unit.  The fan would run intermitently, half heartedly, then finally nothing.  Cost about $800.  Six months later, same problem, except I get zero fan.  Zip.


    Not the fuses.  What is wrong with this thing?!

Check the wire harness connector on the final stage unit for loose connection before replacing the final stage unit/blower resistor. I just fixed mine and found a loose connection. Good luck!

Blower for heater ac not working


First of all check your fuses for the blower fan. If this seems alright, then check on the fan control switch. if not remove and see if the rheostat is faulty. loop to confirm or if not you will need to remove the blower unit for confirmation of the axial fan. Try and check one by one to get to the fault finally before you pull out the entire unit. hope you try this out.Good day

Lincoln mark 8, a/c was working, then kept starting and stopping now dead, compressor works, fan wont blow, even on vent or heat....where is the fuse/relay for this or what else could it be?


It is the blower motor,or the blower relay module,near the blower motor,and check the ac/heat control unit,if the blower ,and relay module turn out to be good.

No heat or air comes out and was told that the blower motor control was inoperable. Do I need to replace the entire blower motor or is the blower motor control a separate part?


If you have no heat blowing and no force of air in AC or blower mode , your blower motor (fan portion) under dash is the likely culprit. Check your fuses before diving in. As the motor wears the carbon brushes wear out.
A common symptom is that the motor starts and stops going over a bumpy road where its brush connection is intermittently bounced on and off.
If you only have alow or intermediate speed , that would be linked to the speed and motor controls.

2002 530i bmw blower motor stoped working


Common problem. Most likely culprit is the "Blower Motor Resistor/Regulator; AC Final Stage Unit" Will cost you around $80-$100 for the part if you put it in yourself.

My ac is blowing at various strengths no matter what setting


the final stage transistor(blower resistor) has failed most likely. It controls blower speed from a signal from the ihka (a/c control panel). the final stage receives the signal from the ihka of drivers preference blower speed. the final stage pwm (pulse width modulates) the blower motor. which means it turns it off and on very quickly to speed up or slow down the blower motor speed. It isn't the easiest part to replace. Usually at a dealership i would expect to pay somewhere around $600 (including diagnosis)but don't hold me to it. bmw dealerships stand behind their repairs and usually include a warranty with the part of 2 years unlimited mileage.

BLOWER PROBLEM


What do you mean by "blower"? Is it the radiator fan or the fan inside the cabin that is for heating and ventilation?
