Have an 07 convertible. Had the passenger side door speaker replaced along with the bass unit. The next day
I noticed a message saying top not secure and the trunk lid won’t open. Once in a while the trunk will open with the fob. The sensor unit above the driver side windshield looks brand new . I did clean it rather good. Have read several articles regarding this matter but none help. My belief is that the mechanic who fixed the speaker and bass unit hit some wire or somehow may have did something to the fuses. I haven’t a clue other than he must have done something. It’s been fine the whole time I’ve owned the car. This all started after he worked on the stereo. Any advise would be greatly appreciated. Thank You.

Welcome to the forum. I'd take it back and ask him what he did and what areas he was in.
