How do you stop top button from chimeing on a 1990 500 sl?

Answer 1

The reason for the chime is that there's an error in your system, somewhere....

It could be a couple of things:

1. low hydraulic fluid

2. one (or more) of the hydraulic valves is leaking

3. there's a sensor above the windshield ...it's directly above the rear view mirror on the windshield frame. This sensor tells the system that the top is properly sealed.

You should check the fluid level of the system...the reservoir is located underneath the spare tire, and under that big plastic hat...there are 2 or 3 10mm nuts you remove to access it.

You might also want to check the window posts to see if there is any sort of oil residue...also check the rear valves as well...you have to hunt underneath the top cover for them.

If the above doesn't help, you're probably going to have to visit your MB dealer and have them run a computer check on your system. That will tell you the exact problem....or all they might have to do is re-set the system.
