Hi ..did I ever figure it out everything I explained just halpen to my 2000 Buick lasbre custom and only difference is I touch a hot wire to one the wires in door windows and it sparked and shut all power to doors now says unknown driver the car drives good ..i cord all fuses everything is good I power surged somthing and blew a fuse or module ..is wat I'm thinking but fuses r fine and relays ..
The answer to all these problems is definitely the body control module, BCM.. It controls every aspect that is giving all the symptoms and complaints. It is a little black box somewhere under the dash. Usually under the steering column on the driver side that has three plugs sometime for plugs that are different colors that are very inexpensive and easy to change and it will solve so many problems that it will be definitely worth the price to fix it. The only issue about changing the BCM is that you have to reprogram your keys to fit that BCM. . But that is not a problem. As long as you can follow the relearn procedure that you may find on other places on the internet that gives you step by step instructions on how you can do it yourself. The BCM's go for around $40 used. Just remember to get the one that matches your car.

Thanks, been busy for awhile. Just did the upper and lower intake job a week ago, put it off long enough I guess. 😆 Hope all is well!
New water pump and metal elbows while I was there too.
