Question about 2003 Nissan Altima
My vent fan only works when set to the highest setting (4), otherwise nothing! I am guessing it is a failure of the switch - do I have to remove the whole dash or can I just remove the fan knob panel? Also it seems that even on high sometimes there isn't much heat (although not 100% sure about this - mentioning it just in case). Any help would be appreciated!
On your Vehicle the problem for the FAN speed is NOT the FAN switch.
99.9 % of this problem on cars is the BLOWER MOTOR RESISTOR.
The blower motor resistor give the speed to the Fan.
But on High speed the switch make a By pass of the switch using a Relay for the high speed.
The Blower motor resistor, is located Beside of the Blower motor On the passanger compartment.
If you replace the blower motor resistor you have 99.9% of this will solve your problem.
