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.

    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.

    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.

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