Hvac blower will not turn on

The blower will not operate, the control panel is on and calling for air. The rear blower will work. Is it a relay? We had a problem for a while where the blower would only blow high and would not turn off with the control panel. then all worked fine for a few months. Now no blower.

Just returned from the Dodge Dealer, if the Resistor fails, its because the blower motor is drawing too many amps, heating up and causing the resistor to get hot and fail. The quote I got to do the repair was over $550.00, Blower motors can be purchased on Ebay for under $100.00 and the resistor depending on your VIN number are as low as $13.00. Dodge told me that their labor rate is over $100.00 per hour so decide for yourself if you would rather do the repair or pay them to do it.

Could be the switch or the blower motor itself went out.

I have a 2006 Pontiac g6 gt and my heat or air will not turn on or rear defrost


You have a computer controlled HVAC system ! It has the capability of setting DTC'S - diagnostic trouble codes !
The HVAC control module is a non-GMLAN device that interfaces between the operator and the HVAC system to maintain air temperature and distribution settings. The battery positive and ignition 3 voltage circuits provide power to the control module. The HVAC control module during defrost mode will change the A/C compressor LED status from on to off. The control head displays recirc, outside air, A/C and rear defrost feedback status through LED indicators. The control head has a rear defrost request switch please refer to Rear Window Defogger Description and Operation in Stationary Windows for operation. The HVAC control head will display NO COMMUNICATION when checking DTCs or doing a vehicle diagnostic system check refer to Diagnostic Trouble Code (DTC) List - Vehicle and Diagnostic System Check - Vehicle in Vehicle DTC Information.
The rear window defogger system consists of the following components:
?€¢
Body control module (BCM)


?€¢
Heating, ventilation, and air conditioning (HVAC) control module


?€¢
Rear Defog relay


?€¢
Rear window defogger grid


Your probably better off taking this to a ASE certified repair facility ! You probably have bad Heater / A/C control panel . HVAC Control Module Malfunction

Blower motor not working on 2005 buick lacrosse cxl


Blower operation is handled by the HVAC control module which gets its power from the 10A HVAC fuse in the instrument panel fuse block. There is a blower motor control processor that gets its power from the 30A BATT MAIN 4 fuse in the underhood fuse block. The HVAC control module sends speed signals to the blower motor control processor which turns on the blower motor at the selected speed. Note that there is no relay involved. If you check the fuses and check the path to the blower motor you may find that the motor is OK and the trouble is somewhere else

Got a 207 chevy tahoe ltz--rear air works ---front air does not work. any suggestions?


"2007 chevy tahoe ltz--rear air works ---front air does not work." Hi! I guess you are referring to the front hvac blower not blowing air at any speed and not coming out at any vents at any mode position. If this is the case, you can start with the fuses at the underhood fuseblock. Check out the three hvac labeled fuses. If found okay, and the hvac controller on your dashboard seemed to be working normally, you better check out your front hvac blower motor underneath the right IP section. You need to verify if power is reaching your front hvac blower when requested by the a/c blower controller. I hope you get lucky. If this is not for you, perhaps a few more detailed symptoms would be helpful. : )

A/c blower blower motor got no power trying to locat the relay?


There is no relay, first check all of the HVAC marked fuses in the rear fuse panel. If fuses are good, problem could be a bad blower motor or the blower motor resistor pack. If this is Automatic Digital HVAC, then that has a Blower Motor Control Module.

I have a 2006 Grand vitara and the A/C or Heater does not blow air. What part is responisble for this.


FIRST CHECK HVAC FUSE AND BLOWER MOTOR FUSE AND RELAY.IF BOTH CHECK OUT OKAY PROBLEM COULD BE HVAC CONTROL SWITCH OR MODULE OR THE BLOWER MOTOR IS BAD.TO KEEP FROM SPENDING ALOT OF MONEY.THE HVAC CONTROL MODULE CONTROL SWITCH VERY EXPENSIVE.IT COULD COST $300.00 TO $400.00 DOLLARS.WHAT I WOULD DO IS REMOVE BLOWER MOTOR IN THE LEFT REAR TRIM PANEL.HOT WIRE TO BATTERY USING JUMPER WIRES.IF BLOWER MOTOR RUNS ITS THE HVAC SWITCH.IF BLOWER MOTOR DONT RUN REPLACE IT.IF THE HVAC IS BAD BEST FOR DEALERSHIP TO CHECK IT OUT.BECAUSE YOUR DASH HAS AIR BAGS IN IT. WHICH WOULD BE DANGEROUS.

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 AIR-BAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY OR DEATH OR DEATH.

NOTE: The blower motor is located on the passenger side of the vehicle under the instrument panel. The blower motor can be removed from the vehicle without having to remove the HVAC housing.

  1. Disconnect and isolate the negative battery cable.
  2. Remove the passenger side cowl trim panel.
  3. Position the carpet to access the front upper screw that secures the air inlet housing.
  4. Remove the recirculation door actuator.
  5. Disconnect the blower motor wire lead connector from the blower motor resistor or power module, depending on application.
    1. Remove the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing.
    2. Remove the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and remove the lower HVAC housing.
    3. Push the rubber grommet through the opening in the lower air inlet housing.
    4. Route the blower motor wire lead through the opening in the lower air inlet housing and remove the lower air inlet housing from the vehicle.
    5. Position the recirculation-air door as necessary to access and remove the three screws that secure the blower motor to the lower half of the HVAC housing.
    6. Gently flex the recirculation air door downward to gain access to remove the blower motor from the HVAC housing. NOTE: To aid in installation, note the position of the blower motor mounting tabs prior to removal
      1. Remove the blower motor from the HVAC housing by rotating and tilting the blower motor as necessary.
      INSTALLATION

      1. Gently flex the recirculation-air door downward to gain access to install the blower motor into the HVAC housing.
      2. Position the blower motor to the HVAC housing and tilt and rotate the blower motor as necessary to install it into the HVAC housing.
      3. Align the blower motor mounting tabs to the locations noted during removal and install the three screws that secure the blower motor to the HVAC housing. Tighten the screws to 2 N·m (17 in. lbs.).
      4. Route the blower motor wire lead through the opening in the lower air inlet housing and seat the rubber grommet.
      5. Position the recirculation door pivot shaft into the lower air inlet housing and install the inlet housing.
      6. Install the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and the lower HVAC housing. Tighten the screws to 2 N·m (17 in. lbs.).
      7. Install the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing. Tighten the screw to 2 N·m (17 in. lbs.).
      8. Connect the blower motor wire lead connector to the blower motor resistor or power module, depending on application.
      9. Install the recirculation door actuator.
      10. Reposition the carpet.
      11. Install the passenger side cowl trim panel.
      12. Reconnect the negative battery cable.
      13. Perform the heater-A/C control calibration procedure.
