The Blower Motor Resistor Pack is defective. Replace it.
under dash on pasenger side
You have a bad blower motor resister.........
Could be a bad resistor pack at the blower motor Could be a bad low speed relay
Could be hi-speed fan relay or secondary winding in blower motor
Check the resistor if it only works on high Check the resistor if it only works on high Check the resistor if it only works on high
A faulty camshaft can cause your 1991 Nissan Maxima to idle erratically. A diagnostic test could verify the cause of the improper idling speed.
It is the resistor, replace it.
blower motor resistor thermal limiter is blown. Replace the blower motor resistor.
The type of wind that blows at high speeds at altitudes above 12 km is called the "jet stream." Jet streams are narrow bands of strong wind in the upper atmosphere and can have a significant impact on weather patterns and aviation routes.
The PCM limits the top speed of the vehicle by cutting back on the fuel if the engine RPM's are high enough to damage the engine
The low and medium speeds run thru a resistor. The high speed runs thru a relay. The relay or possibly the switch itself may be bad.
More than likely the blower motor speed resister is shot. This part is available at you local auto parts store.
