BMW 325i Problem Report
BMW 325i Blower Final Stage Fan Resistor May Fail
The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.
Fan was intermittent. Dealer told me my blower resistor (final stage unit) has gone bad and the repair would cost $350. Didn't have the dealer perform that repair. Bough part online for $65 and found DIY online. Took 45 mins. - Visitor
Blower motor keeps running after you turn car off and running. Battery. Down - Visitor
Air conditioner/heater hisses as if it's coming on, but blows no air now in either mode. Is this an easy, inexpensive fix? - Visitor
Blower fan resistor failed. When I switch on my AC the speed does not increase or decrease. A local technician got a new blower resistor and replaced it for - Visitor
AC/Heater blower will not work - harleyf150
The blower speed varies up and down while driving with the AC on. Sometimes the blower will fail to operate at all. I have not had it repaired yet. - wayneman01
Blowwer final stage resistor failed. Fairly easy to replace not an expensive part. Problem was I could not control fan speed. - Visitor
The heater blower does not work and blows cold air continually. I replaced the resistor back about a year ago. Do you have any suggestions for this. - Visitor
variable blowing, sometimes not at all, then finally just stopped working altogether. $500 for part and labor at a BMW dealer - Visitor
heater will work but my car warms up and i turn off the engine then turn it back on it doesn;t work at all - Visitor
The fan is only blowing at the lowest speed - jmonk
fan stopped working but you can hear the car changing when ac is turned on so i believe it is just the fan. - Visitor
replace final stage unit. - kenvanos
Fan for A/C and heater will not turn on at all regardless of settings. - Visitor
Fan speed would vary and one day it just stopped working. Dealer said it needed a new blower motor and fan resistor for a total cost of $1.700. - Visitor
My ac/heat would work some days and others it wouldn't for a couple months until it just completely stopped. The blower motor was working fine so it was ruled out. Turned out to be the FSU(blower motor resistor). - Visitor
fan keeps running after car has been turned off. - Visitor
Went out randomly and replaced it works now. - Visitor
Blower began surging, then shutting down entirely, then picking its own speed, and finally and instance of "run-on" after the ignition was turned off. (If that happens, pull fuse No. 50 so your battery is not drained. - Visitor
replaced resistor - Visitor
