seatbelt/headlight/key warning buzzer
This past weekend the warning buzzer on my 88 300TE started to sound very sick then went out completely. While losing this annoying noise is not really a bad thing, I would like to trouble shoot the problem and fix it just to avoid the possibility (inevitable) of a dead battery from the lights being left on. Where is the relay/buzzer located, is it a simple fix (R/R) and can the buzzer be replaced with a different tone? What other systems are bad also? By the way is this a common failure on the 124?
Thanks in advance.
