Report: Blower Final Stage Fan Resistor May Fail
BMW 328i Problem
Model Years Affected: 1997, 1999, 2000
Average Mileage: 140,011 mi (65,000 mi - 218,000 mi)
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.

EnthusiastThe air conditioner would work, and you could tell it was cold but the air would not blow out of the vents. Also this would happen off and on for about 6 months. The air conditioning would work and blow cold air, then it seemed like on the really HOT days it would not blow the cold air at all, so i had enough!!! Replaced the final stage transistor and Yeah that fixed the problem!!!!!!!!!!!

A/C starts and stops unpredictably as if a connection is loose.
Perhaps I will have to try replacing the final stage fan transistor whatever that is.Flag ThisLike0 -

Blower goes on intermittently. They want to replace whole resistor for $400+

the a/c would turn on when it wanted,first i thought it was a loose connection point, wrong! I'm now going to replace the final stage resistor, pray to god. I live in Las Vegas, and it's HOT!!!!!

AC/Heater fan only works sporadically and almost never when you need it. No solution
