1991 300D 2.5 Turbo

Looking for information on the aux fans. Do both units work at the same time? My drivers side unit is working, however the passengers side never seems to spin. Any thoughts?

Broken belt. The driver side fan has a motor and the passenger side fan is a rider.

Are you sure? I think a 91 124 has two electric fans. The plug looks like it is for one fan, but when removed it splits into a Y and powers each fan. At least on m103 version.
