Im trying to locate the fuse for the rear blower in my 2008 gmc arcadia, can anyone help me


RR/HVAC fuse 30amp located in the under hood fuse box. You can check it but highly doubt it's the problem . More then like it's the blower motor control module that's bad .
Circuit/System Description
The auxiliary blower motor is a variable speed fan. The HVAC control module controls the fan speed by sending a pulse width modulated signal to the auxiliary blower motor control module. The auxiliary blower motor control module varies the duty cycle across the auxiliary blower motor in relation to the pulse width modulated signal. The auxiliary blower motor speed can be adjusted from 10 percent to 90 percent duty cycle (PWM), 90 percent is high speed fan.
Watch this video for testing purpose's only , this is a front blower motor control module . Same way your back one works . GM is GM Chevy , Buick ,GMC , Cadillac .

Can anyone tell me where the fuse and/or relay is located for the blower motor on a 2005 Buick LaCrosse


First off , does it work on any speed ? After looking at a wiring diagram I find out your vehicle has a Blower motor control processor , a module ! That is your problem ,more then likely !
DEFINITION: The blower motor is inoperative in all speed positions.

1

Did you perform the Diagnostic System Check - Vehicle?
--
Go to Step 2
Go to Diagnostic System Check - Vehicle

  1. Turn ON the ignition, with the engine OFF.
  2. Place the blower switch in each speed position.
Does the blower motor operate in any of the speed positions?
--
Go to Blower Motor Malfunction
Go to Step 3

3

  1. Turn OFF the ignition.
  2. Disconnect the blower motor connector.
  3. Turn ON the ignition, with the engine OFF.
  4. Connect a test lamp between the blower motor supply voltage circuit and the blower motor control circuit.
  5. Place the blower motor switch in the minimum speed position.
Does the test lamp illuminate?
--
Go to Step 9
Go to Step 4

4

Test the battery positive voltage circuit of the blower motor control processor for the following:
?€¢
An open


?€¢
A high resistance


?€¢
A short to ground

Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?
--
Go to Step 15
Go to Step 5

5

Test the ground circuit of the blower motor control processor for an open or a high resistance. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?
--
Go to Step 15
Go to Step 6

Important: Ensure that the blower motor control processor connector and the HVAC control module connectors are connected during this step in order to avoid misdiagnosis.

  1. Measure the voltage from the blower motor speed control circuit at the HVAC control module to a good ground.
  2. With the ignition ON, turn the blower motor to high then to OFF.
Does the voltage measure near the specified values?
5 V OFF
1 V ON
Go to Step 10
Go to Step 7

7

  1. Turn OFF the ignition.
  2. Disconnect the HVAC control module.
  3. Turn ON the ignition, with the engine OFF.
  4. Measure the voltage from the blower motor speed control circuit of the HVAC control module to a good ground.
Does the voltage measure near the specified value?
5 V
Go to Step 11
Go to Step 8

Test the blower motor speed control circuit of the HVAC control module for the following:
?€¢
An open


?€¢
A short to ground


?€¢
A short to voltage

Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?
Go to Step 15

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

Cooling fan 98 cavalier inop


This system is controlled my the power control module. when you need it the system sets a ground to the system
you can run a ground to the blower motor and it should come on. but you will need to put some kind of switch on it to cut it off so it will not kill your battery or just replace the 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.
