in my haines manual it does not say it controls the rear defogger, however it says it controls the fog lamp switch, door lock relay, park brake ind., fog lamp relay, high beam ind., headlamp relay, headlamp switch, auto light sensor sig., auto light sensor ref.. I replaced my body control module(01 impala ls 3.8) because i was told it was the cause of all my lights inside and out flickering, already replaced alternator before that. problem still persists. replaced negative battery ground wire also. The bcm is very easy to replace but needs to learned by your ecm. The dealer would have charged me 400-500 bucks. I bought the bcm from napa for 80.00 and programed it without a scan2 tool like everybody told me i needed. but like i said didn't solve problem, just throwing away time and money. Massive amounts of complaints are out ther for this problem for the impala and Monte carlo01-02. but Chevy will not recall because apparently it is not a safety issue. however ther is a technical service bulletin #010603005
My 97 Buick defogger module is in the rear leftinside panel.
It is under the dash near the steering column.
by the EGR valve on passenger side of engine
its located on driver side head on top of block little black module with plugwire running out of it

There is no such thing as a bypass module. The best I can figure is the Body Control Module. If this is the case then you will have to find a shop with a scanner to do it. If you have NOT made the necessary repairs then the light WILL come back on.
The letter c stands for the defogger relay wich is located under the dash on passenger side
On a 2004 Chevy Impala, the traction control sensor is located in the ABS pump module. On the driver side of the car, the sensor is located at the left center of the engine compartment with black wires hanging from it.

The ignition module on a 2002 Impala is located in part of the electrical system. In some cars, the module kept the car from starting. When the key was turned there would not be a clicking noise. The module works with the passlock system of the car.

Need to know which control module in question.
I know one thing it does. My air conditioner wouldn't come on. The replacement of the module fixed the problem but now the radio is locked. The dash indicator light that said a door was open when it was not is now working properly. Seems to control quite a bit of the car.
Look under the dash by the drivers left foot kick panel. It is a rectagular box with three cables going into it
Nope. One is a relay, the other is a control module. The control module TELLS the relay when to operate.
What does the general control module control
on my 2003 GMC 2500 there is a control module inside the heater duct work on the passenger side. It is easy to access and replace with a couple of screws. Replaced mine and fixed the problem.
How do I test body control module and is it hard to do..
the ignition control module is operated by the pcm,the pcm tells the ignition control module when to energize the coils to enable spark
The BCM (Body Control Module) of the Passlock system is malfunctioning. It will need to be replaced. I just had it done to my '03 Impala.
