My 2000 323Ci blower is turning on and off. If the AC is on, i can hear the release of the freon, but the blower comes on and off randomly. Will replacing the final stage resistor fix this problem?
this is a very common issue with our (E46). just make sure when the blower dies down that the air cond display for the blower speed stays lit with the same amt of bars, ie when your hvac is on auto it will change automatically.
good luck
