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

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.
