I've got a clicking noise from the glove box area on my black 1991 164S with the key on and the head lights on. No noise when the head light switch is off. Also, recently the chime continues when the key is removed and continues until the drivers door is shut. I swapped out N22, no change, but it felt like the clicking was coming from N44, so I swapped that out this morning again no change. With the head light switch off, the turn signals work normally. However, with the headlights on, the right turn clicks much faster than the left.
