In my 1987 300D the seat belt warning light comes on while driving (when I am belted in). I have replaced the overhead courtesy light console this is housed in, and checked the wiring in the area.

Also this occurs more when wet/damp outside. I suspect a short in the wiring circuit, but wanted to hear if others have had this problem and what a possible solution may be (before I remove the bulbs permanently).

Thanks

I experienced the same thing for some years, every once or while. Checked everything, could not even reproduce the appearance when I wanted it. May be the whether conditions are the problem. I have my cell phone under strong suspicion. No fix that I know of.

i belive there is a relat that controls dome lamp and door chime operation ,if this relay is bad can cause an intermittent seat belt lamp filcker.

i could be wrong

DSMIT,

If this is the same relay, would this not also sound the warning chime as well?

Basically it flickers on/off w/o the door chime.

Does the courtesy light comes on with the warning light, even for a moment?

Does the warning light work properly otherwise? That is, does it blink for about 15~20 sec when you open the door, and then turns off?

Did you check your door switch for rust/false contact?
