the lite is red between the up-down buttons when the ignition key is in on position,always. top can only be manually operated. the shelf in trunk is in the lower position. any electrical troubleshooting or advice would be helpfull; motor,connections,switches, etc.

Asked by for the 2003 BMW Z4
THESE ARE VERY COMPLICATED I REC YOU SEEK HELP. DO NOT TRY TO REPAIR YOURSELF!!!!!!!!!!!!!!!!!!!!!!
you seem to be just pushing dealer or mechanics sales instead of even an intelligent answer. if this site is just that no thanks. sorry for wasting my time

you can guess all you want to but REALLY this is beyond you. im telling you facts if you don't believe me go ahead and guess till your pocket book is dry
your non response to a direct question reaffirms my previous opinion! I am just asking for help to avoid the dealer, and other shops to fix this problem. obviously you have no aswer that is credible, or just do not have the expertise to solve any problem,other than to send me to a dealer or shop to rip me off; since you gave me no info. at all. NOW I SEE WHY YOU ARE THE MOST RESPONDANT SO CALLED MASTER MECHANIC TO RESPOND. I DID NOT GUESS AT ANYTHING AS YOU SUGGEST, AND I NEVER RECEIVED ANY FACTS THAT YOU CLAIMED YOU FORWARDED; IN FACT YOU JUST RESPOND TO ANYTHING WITH ABSOLUTELY USELESS JIBBERISH.
THAT MAKES ME LEARY OF ANYONE CLAIMING TO BE A MECHANIC ON THE INTERNET, NO LESS EVEN MASTER.
STOP WAISTING MY TIME WITH ABSOLUTELY NO HELP!
THIS MESSAGE IS NOT TO YOU BUT FOR ALL THE OTHER PEOPLE WHO MIGHT SEEK HELP ON THIS SITE IN VAIN- OTHER THAN TO SEEK YOUR SPONSORD HELP!!!

I had the same problem with a 2003 Z4 everybody said don't fool with it take it to the dealer WOW $ they wanted $1250.00
I started with replacing the micro switch very simple not expensive and that didn't work so I took the module from under the glove box and sent it to a guy in California he rebuilt it I think with shipping it was $90.00 it work for about two months and then stopped so took it to BMW, WOW they wanted $3450.00 to fix it but no way so I took the conv/top motor out about a days work without help took the motor to a starter/generator rebuilder shop $28.00 put it back another days work that was eight years ago been working ever since.
