96 SL320 Hard top Chimes

[bwheitman]

Funny problem, When I go over big bumps, or back out the driveway at an angle, I get a chiming sound, I didn't know what it was at first and then noticed the soft top switch lighting up. It only does it when the hard top is mounted. Is this normal? Any ideas on what I should check first? The car has never been in an accident, but had the windshield replaced. All the top controls function properly. Thanks for your help!

Does the light stay "on" or does it flash out a code?

It doesn't stay on, just for a minute, like if I am backing out of the drive and I turn the car at a steep angle the thing chimes and the light comes on. After I get the car leveled out again it goes out. It is the same thing that happens if your at a stoplight and putting your top up or down and you start moving, it is that alarm. I think there is a latch that is maybe losing it's grip? Then when the body flexes, it becomes lose? If that is the case then it is the potential that the latch will fail. None of them leak or malfunction, but it could be a switch in one of the latches?

the intermittent nature indicates either a lock/latch is not quite in place, or the microswitch that senses its position is not adjusted or sensing the position properly.

Hi I had this problem with my '91 300SL. (This, I believe, is a warning chime to say the roof is not completely locked down, so not to drive). Inside the boot, at the top of the back wall both sides, there are the locking levers behind plastic covers. I had already locked the hard top down when the chime started when driving. I used the manual closing tool to lift the left lever one click, then clicking down again whilst leaning down on that corner of the roof at the base just above the boot. Get someone else to push down whilst you click down with the tool. I repeated this on the right side and it did the trick, no problems since, although I have not taken the hard top off since. Good luck, I hope this helps you-Matt

Thanks Matt, I removed my hard top and checked everything out hte best I could. Then this morning on the way to work I was going around a curve, hit a bump and the thing started chiming and the switch was blinking. It did not stop until I hit another bump, so I am going to take a look in the boot behind the trim like you said and see if there is a sensor switch or something out of adjustment. It is ok when I am in the car, but with a passenger they start freaking out, ha ha.. Thanks again everyone!
