Hi, i need to fix the driver's lock on my 1992 300CE as it failed to operate, the lock is partly di-assembled. Is there anyone who deals with these kind of repairs? Does it need a new one? Costs? I will appreciate your answers, i am in Seal beach, 20 miles radius is ok to travel except there is an alternative solution. Also, in the same location, someone knows an autoglass repairer because i recently had a damage on the windscreen, approx. 12 inches. Thanks
