Passenger side belt will not come out...Sometimes it works, sometimes not
Any ideas on repair?? Maybe what's causing it??

Also my 1991 500sl has a connector for some kind of a meter under the hood.
I am not a mechanic but if there is some type of meter available to read problem codes for this car, I would like to get one......I know it's too early a model for ODB2 meter. How about an odb1 meter or a predecessor??

I'v e been searching the site for a couple of weeks and can't find anything on the belts....maybe a relay or something??

Thanks
