programming the body control module

I'm pretty certain that my body control module on my 01 Monte SS is bad. What do I need to re-program it? If I need to replace it, I can get one used for $50.00 but I'm told it will still have to be reprogramed. Do I have to have the dealer do this?

hate to tell you this but you cant use a used bcm (body control module). they are programmed with cars vehicle id number and once programmed they are locked and cant be changed. must use new bcm and has to be programmed by the dealer with a tech2, sorry for the bad news. by the way the bcm's on these cars were junk, they came out with new part number and i havent had any problems with them so far, good luck

Thanks for the input. I have been offered many used BCMs onlne. Since the BCM can't have the VIN reprogrammed, why are these parts people making this used part available? The dealer wants $185.00 for the part, plus time to reprogram it. What are the chances that the existing BCM can be reprogramed? How prevailent is this problem? Would you suggest a dealer anyway?

i dont know why they are trying to sell you a used bcm, i work in a chevrolet dealership and know for a fact that after 35 key cycles a bcm is locked and cant be reprogrammed. (gm sent out a bulleting about this because people werent setting options during setup and shipping vehicle, and after they came back complaining it would already be past 35 key cycles and they would have to install another bcm). like i said in previous post original bcm's had numerous problems and they came out with a new part number and havent had any of those come back with problems. It may seem like a big expense but will save you time and aggrevation in the long run. So yes i suggest you take it to the dealer and have it repaired. Hopefully your dealer has a decent electrical tech that knows his stuff.
Good luck

Thanks! Nice explaination. You would think though, that if the had a crappy BCM, and later brought in a better onbe, they would work with the customer on price. This is a crappy way to run a railroad. Even the mid-shaft steering problem is unacceptable. They learned they had a problem, but make the customer pay for it. I'm about done with GM.. Thanks again.
