I have to replace fan resister on my 2000 pontiac Montana do I to take out the blower motor to get at the resister


Step 1: Pry and remove the retaining pins (3) that secure the interior panel to the UNDERSIDE of the glove compartment area (near the PASSENGER'S feet).

Step 2: Disconnect the blower motor's wiring harness (1).

Step 3: Loosen and remove the 7/32 mounting bolts (3) that secure the blower motor to the vehicle. Pull the blower motor from the vehicle.

Step 4: Disconnect the wiring harness (1) mounted just to the LEFT of the resistor.

Step 5: Loosen and remove the 7/32 mounting bolts (3) that secure the resistor to the vehicle.


NOTE: You only need to LOOSEN the rear bolts, as the resistor will slide free without completely removing them!

Step 6: You can now slide and remove the resistor.

Step 7: Mount the new resistor by tightening the 7/32 mounting bolts (3). Connect the wiring harness (1).

Step 8: Reattach the blower motor by tightening the 7/32 mounting bolts (3).

Step 9: Connect the blower motor's wiring harness (1).

Step 10: Re-engage the retaining pins (3) to secure the interior panel to the UNDERSIDE of the glove compartment area.

Only hi speed on ac blower motor


This problem is caused by a burnt out Blower motor speed control resistor. The part is near the Blower motor and is held into the air duct by two small hex head screws. The part is chap and easy to replace.

2005 Jeep Grand Cherokee. Htr/AC fan switch only functions @ highest speed. At lower speed settings I can hear doors opening and closing---but not air.


replace the blower motor resistor. It controls the fan speeds. It defaults to high speed only when it fails.

How to replace the blower motor resistor block: Caution: Stay clear of the blower motor and resistor block (Hot). Do not operate the blower motor with the resistor block removed. 1. Disconnect and isolate the battery negative cable.
2. Remove the glove box from the instrument panel.
3. Pull out the lock on the blower motor resistor wire harness connector to unlock the connector latch.
4. Depress the latch on the blower motor resistor wire harness connector and disconnect the connector from the resistor.
5. Remove the two screws that secure the blower motor resistor block to the HVAC housing.
6. Remove the resistor block from the HVAC housing. Installation:
1. Position the blower motor resistor block into the HVAC housing.
2. Install the two screws that secure the resistor block to the HVAC housing. Tighten the screws to 2.2 Nm (20 in. lbs.)
3. Connect the wire harness connector to the resistor block.
4. Push in the lock on the blower motor resistor wire harness connecgtor to lock the connector latch.
5. Install the glove box.
6. Reconnect the battery negative cable.
7. Have a nice day!

Blower motor wire harness


Links show replacement of the resistor and wiring harness. Second link is to RockAuto where you can buy the resistor with a harness. Apparently (from the first link), Amazon also has the resistor available with the harness.

Blower fan only works on high speed


Its the blower resistor. I couldn't get the pictures in sorry. Rob

RESISTOR-BLOWER MOTOR
DESCRIPTION
The blower motor resistor is mounted to the HVAC air
inlet housing, directly behind the glove box. The
blower motor resistor consists of a molded plastic
mounting plate (1) with an integral wire connector
receptacle (2). Concealed behind the mounting plate
are coiled resistor wires contained within a ceramic
heat sink (3). The blower motor resistor is accessed
for service by removing the glove box from the instrument
panel.
The blower motor resistor is accessed for service by
removing the glove box from the instrument panel.
OPERATION
The blower motor resistor is connected to the vehicle electrical system through a dedicated wire lead and connector
of the HVAC wire harness. The blower motor resistor has multiple resistor wires, each of which will reduce the
current flow through the blower motor to change the blower motor speed.
The blower motor control in the MTC heating-A/C system directs the ground path for the blower motor through the
correct resistor wire to obtain the selected speed. With the blower motor control in the lowest speed position, the
ground path for the blower motor is applied through all of the resistor wires. Each higher speed selected with the
blower motor control applies the blower motor ground path through fewer of the resistor wires, increasing the blower
motor speed.
The blower motor resistor cannot be adjusted or repaired and, if faulty or damaged (such as a cracked ceramic heat
sink), it must be replaced.

DIAGNOSIS AND TESTING
BLOWER MOTOR RESISTOR
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in accidental airbag deployment and possible personal injury or
death.
NOTE: For circuit descriptions and diagrams, refer to the appropriate wiring information. The wiring information
includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness
routing and retention, as well as pin-out and location views for the various wire harness connectors,
splices and grounds.
1. Disconnect and isolate the negative battery cable.
2. Disconnect the wire harness connector from the blower motor resistor (Refer to 24 - HEATING & AIR CONDITIONING/
CONTROLS/RESISTOR-BLOWER MOTOR - REMOVAL).
24 - 138 CONTROLS ND
3. Using an ohmmeter, check for continuity between all of the blower motor resistor terminals. In each case there
should be continuity. If OK, repair the wire harness circuits between the blower motor switch and the blower
motor resistor or blower motor as required. If not OK, replace the faulty blower motor resistor.
REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in accidental airbag deployment and possible personal injury or
death.
WARNING: The blower motor resistor may get very hot during normal operation. If the blower motor was
turned on prior to servicing the blower motor resistor, wait five minutes to allow the resistor to cool before
performing diagnosis or service. Failure to take this precaution can result in personal injury or death.
1. Disconnect and isolate the negative battery cable.
2. Remove the glove box (Refer to 23 - BODY/INSTRUMENT
PANEL/GLOVE BOX - REMOVAL).
3. Disengage the wire harness connector locking tab
and disconnect the wire harness connector (1) from
the blower motor resistor (2).
4. Remove the two screws (3) that secure the blower
motor resistor to the HVAC housing (4).
5. Remove the blower motor resistor from the HVAC
housing.
INSTALLATION
1. Position the blower motor resistor (2) into the
HVAC housing (4).
2. Install the two screws (3) that secure the blower
motor resistor to the HVAC housing. Tighten the
screws to 2 N·m (17 in. lbs.).
3. Connect the wire harness connector (1) to the
blower motor resistor and engage the wire harness
connector locking tab.
4. Install the glove box (Refer to 23 - BODY/INSTRUMENT
PANEL/GLOVE BOX - INSTALLATION).
5. Reconnect the negative battery cable.

1981 corvette blower motor getting no powere has power at fuse block but no where else blower motor runs with jumper wire


Check the blower speed control resistor pack, it is located in the air stream near the blower motor, that is most likely the cause of the inop blower, but be warned if the blower is drawing to much current due to wear the resistor will fail again, I believe the connector has four wires, 2 are heavy Gage
