BMW Repair: 1999 bmw 328i-Windows & Sunroof opening themselves, antenna amplifier, 1999 bmw 328i


Question
Hello Evan,

I own a 1999 328i, after I leave the car and hit the lock button on my remote, MOST of the time the locks would lock then unlock right away. Im sure this is part of the bigger problem.  Now my big problem is that when the car is off,  the WINDOWS & SUNROOF OPEN BY THEMSELVES as if I held down the unlock button on my remote. Now this can happen right after I get out of the car, or it can happen 10 hours later, very random. It doesnt matter if I lock the car or not. When this occurs, sometimes my locks wont work either.  This happens everyday,  do you have any idea of what this may be?????????

Answer
Fred disconnect the Remote antenna Amplifier in the left rear C-pillar. If the symptoms reoccur with this disconnected then replace the general module behind the glove box and have the module coded by the dealer. Give them both master vehicle keys and request that they be initialized so that remote functions work with the new module. Let me know how it goes.
