This could be the on/off switch, an open in the circuit,a defective relay,resistors, or blower motor itself.

    Each resistor represents a speed. You need the shop manual and a Digital Voltmeter(DVM) to do this. Your basically measuring the resistance of each resistor with the meter to see if their resistance is within spec's or infinity. The shop manual will tell you what each resistors values are.

    BUTin your case its not comming on at all I would make sure it works first. Make A SET OF JUMPER CABLES AND HIT THE BLOWER MOTOR ITSELF WOTH DIRECT B+ FROM THE BATTERY. iF THE MOTOR WORKS THEN ITS THE SWITCH OR THE RELAY. REMEMBER HIGH SPEED BYPASSES THE RESISTORS AND IS DIRECT B+ FROM BATTERY. HINT IF HIGH SPEED ON SWITCH DOESN'T WORK!!!!!!!! Is it the switch or the motor?BuT MAKE SURE MOTOR IS GETTING B+ Eliminate the motor as being the culprit first then concentrate on the switch and relay.

01 grand.prix ac fan switch only works on high. has a duel temp controller when you turn fan off the only way fan comes back on is to move the temp controller levers


Hi!!
When the Blower Motor Resistor (controls blower speeds) goes bad, the blower motor works only on HIGH SPEED. REPLACE IT.
BLOWER MOTOR RESISTOR Removal & Installation
  • Disconnect negative battery cable.
  • Remove right lower instrument panel insulator panel.
  • Disconnect blower resistor connector located behind right side of dash.
  • Remove blower resistor screws and blower resistor.
To install, reverse removal procedure
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

Heater blower stopped working?


Hello,
You may want to try your fan on all speeds. If it will work on high, you have a bad resistor for the fan motor. ( high speed doesn't go through the resistor ).
If it doesn't work on any speed, I would check the following;
1. Make sure the fuse isn't blown for the fan blower motor.
2. Check, or have checked the wires between the fan control switch and the fan blower motor.
3. Have the fan control switch checked.
4. Have the fan blower motor checked.

I hope this helps you.

2005 Chevrolet Silverado - Fan not coming on. When I turn the heater/ac blower fan on, fan does not work. Prior to completely going out, fan would quit working intermittently. Is this a fuse problem? ...


Chk for power at the blower motor electrical connector. If no voltage, check the blower motor resistor, its within the blower motor vent (this controls power to the blower motor). Also, in theses vehicles water may have damaged the blower motor itself. Inspect the blower motor for proper function.

To install:
  1. If the fan was removed from the motor, position the fan on the shaft, then install the retaining nut. Tighten the nut to 12 inch lbs. (1.4 Nm).
  2. Position the blower motor and fan assembly to the module, then install the retaining screws. Tighten to 5 inch lbs. (0.6 Nm).
  3. Connect the cooling tube to the blower motor.
  4. Attach the electrical connector to the blower motor.
  5. On 1993-98 vehicles, install the cross brace bar and retaining nuts. Tighten the nuts to 18 ft. lbs. (25 Nm).
