Hi my name is Allen!

First I need to know if you A/C system is Auto Temp or Manual, because if it is Manual it doesn't have a Blower Control Module. If it is Auto Temp then the module is located on the passenger side under the dash mounted on the A/C Housing.

I can help you better if you tell me what the system is doing and why you think its the blower module. I ask this because this year model had a lot of problems with the BCM which stands for "Body Control Module" and can cause the A/C system to do strange things like the blower on high all the time or the A/C compressor not engaging etc.

For further asistance you may reach me at FixYa!

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 .

2004. Why is the blower motor not receiving power?


The blower motor relay in the auxiliary junction box under the hood is good ? All relays ? only one controls the blower motor ! The electronic automatic temperature control module turns it on by supplying a ground inside the module ! The 30 amp fuse for the blower motor is located in the under hood auxiliary junction box ! At the relay socket test for battery voltage at pins 30 an 86 ,power form 30amp fuse ! The other two pins 85 an 87 ,85 is circuit to the electronic temperature control module . You could test this part of the circuit too , with a test light or volt meter . But if no voltage to the blower motor ,could be the electronic temperature control module is bad !

Where is the body control module (bmc) located at in a Ford Windstar 2002?


pretty sure this vehicle does not have a BCM. most fords don't. there is a module built onto the back of the inside fuse block that is more or less the same thing. a real pain to get out of the vehicle.

I crossed my jumper cables on 1992 LeBaron. Now my headlights and radio won't turn on. I checked the fuses and they're fine. My mechanic said ois might be the Body Control Module. We ordered a used one and...


Why would a professional mechanic ,say what it might
be,then order something,based on nothing?

You always start with a wiring diagram
You check what does work
At some point in your testing,you will find
the problem

You only replace parts when your TESTING
PROVES a part failed

Whilst driving, the heater fan just stopped working, there is heat coming from the vents but no fan to push the hot air around the car.


check your fuses under the dash( or maybe on the passenger side of the dash) - if all the fuses are good, check the relay center under the hood to see if you have a faulty relay. If those a re also ok you may need to change out the blower motor. Your local mechanic can perform these check in a few minutes and probably won't charge you unless something is faulty.

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.

Yes i have juice to the blower motor, but it dont blow all fuses are good, freon is good


Cadillac 1999 DeVille
If the front blower motor is not running with battery level power to it, you may have bad blower resistors which controls the speed of the motor.. Unfortunately the resistors are built-in the motor. You may have to replace the motor. If you remove the motor, you can recheck it by direct wiring power to it. OR you may have loose wires.
Also check the Heater and A/C Programmer module.

Here's some info I found from another posting.

Red is positive 12 volts coming from fuse of circuit breaker. The black wire is either the ground or the main hot wire going to the blower motor (3 pin connection only), and the gray wire (if is is small in size) is a variable voltage coming from the body control module requesting speed for the blower motor.The blower control module varies voltage on the main wire going to the blower motor, supposedly in accordance with the requested voltage from the body control module. Usually if all fuses are okay and present on the apprpriate wire of the blower control module, the a blower motor that will not run or stays running after the key is turned off is the fault of the blower control module. If the blower control module has failed the the cause must be determined (over amping blower motor) or else new blower control module may fail when powered up.Usually blower control modules have more than three wires. Usual connections are: B+ (battery voltage) GND (chassis or engine ground), two large wires going directly to blower motor (can be any color, but are usually 10 guage in size), and an optional wire that reports voltage level back to the body control module.

1997 buick century - blower stays on when car is off


The blower motor relay is stuck, holding the curcit engauged. Look under the hood, find the conveinence center, where you will find fuses and relays (read the cover, see if one says AC/Heater blower relay), if not, look in your car's manual, to see where this relay is located. When you find it, pull it out, see if the moter stops, if ti does , replace it.
