the fan sometimes on, sometimes off,and now it's dead not on at all. Is it the only possibility that blower final stage resistor need to be replaced? or there's other possibility like fan motor?
I have a 2003 bmw 325 i the ac fan wont turn off after my car engine is off
When the car is turned off the floor vents blow hot air including my arm rest vent. I get no light on any of my ac buttons. I thought it would be fuse 9 or 20 but they look fine. I take 9 out and the blower stops of coarse. The only think I can think of is the big porcupine looking fuse on the passenger side under the vent on the floor. Is it an FSU problem?
Final stage resister failure caused fan to continue to draw power after shutting off car. The battery would drain and the alarm would then trigger when set.
blower motor stopped blowing
air wouldn't flow so had it insepected and replaced this part.
Buy the part from Rock Auto (<$40) and go on line and replace it. It takes less than 5 minutes. The repair location is under the passsenger side, unclip and remove and replace. Works like a charm, BMW wanted $200+ to replace.
*I coun'nt figure out why cars battery kept on dying and fans blower would come on and not shut off when you needed it to until I replaced the blower final stage unit, all is back to normal, Thank God..........
It randomly started. Would turn the car off, the blower would stay on and eventually run the battery down. I haven't had it fixed yet, but in the meantime every time I park I have to get into the trunk and unhook the battery cable so it doesn't run down the battery.
blows hot air under the dash while driving and the cluster that controls ac/heat doesnt work at all
Blower output varies constantly and sometimes won't turn on. Had to replacew. $300!
Fan blower stays own after engine shutdown depleting the battery charge.
The blower fan wouldn't cut off and was constantly blowing hot air in the cabin. I took it to one repair shop and they only disabled the fuse and told me I needed a new control module. I took it to another non certified mechanic and they replaced the control module, but the blower fan wasn't turning on
Even after I turn my car off, I still have air blowing out of my vents.
Blower final stage fan resister replacement because fan would not start.
My blower motor stays on even after the car is turned off causing the battery to die out. I need to shut it off how do i do so?
Not fixed yet, fan blows cold on face only when heater on, but will be hot at feet or defrost. Defrost will stay on or turn on after engine shut off.
