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.

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.

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.

Blowwer final stage resistor failed. Fairly easy to replace not an expensive part. Problem was I could not control fan speed.

Air conditioner/heater hisses as if it's coming on, but blows no air now in either mode. Is this an easy, inexpensive fix?

variable blowing, sometimes not at all, then finally just stopped working altogether. $500 for part and labor at a BMW dealer

Blower fan stopped & will not operate in any position. All fuses associated with blower fan were good. Therefore I expect Blawer Final Stage Fan Resistor may have failed

Everything was fine, One day pulled in the gym and the blower stopped working all together, no air at all no noises just a dead unit, 30 mins later it came back on and was fine for 2 months until 2 days ago when it stopped working all together again, all the lights come on and seems fine but there is no air blowing out for hear or AC what so ever, Hoping its the Resistor as I will attempt the repair this weekend

Problem of no air blowing when turn on fan for either air conditioning or heat at all levels and seemed like the indicator is working OK.

fan speed changes to high and will not decrease by using any controls. Must cut off fan by hand.

replaced thermostat(s).both. and radiator reservoir..fixed all the overheating problems, but make sure you Burp the radiator a few times as you fill it up..
When car starts to overheat,even a very slight bit, I would immediately shut the car off. This was happening a I was trying to figure out what the problems were, and realized there were two different thermostats on this vehicle. While the overheating was occuring, i noticed the air conditioner would immediately cease to function. No air out of vents..nothing would fix it. Thought i was having a problem there too. Wasnt. Its a fail safe for BMW to protect engine..while hot.
Now, the same things is happening, and my car is not and has not overheated. Temps are perfect, and all good in that category. But, occasionally, and repeatedly, the blower will not come on to supply air thru vents. what is causing this> i cant figure it out.
