Not true! My courtesy light time delay (1983 300TD) works perfectly but the seat belt buzzer warning is kaput. Fortunately, the headlamp warning buzzer still works and has saved my b*tt on a number of occasions... Any advice?
Umm, rejoice that yours is working right? What advice?
For general information, on many cars the left and right door switches are isolated by a diode so that the left and right floor courtesy lights may be separated. (One of the nice little touches.) This diode resides inside the warning module, which is really just a miscellaneous collection of semi-related electronics, and whose existence explains why there are sometimes odd interactions. -- Jim
