Replaced the bad original fan with this one: Depo 340-55002-200 Condensor Fan Assembly but the fan won't come on . Checked the climate control setting for the fan (left side 20 right side 10). Checked the volt on the (female) connector (that connects to the fan) and it gives me zero voltage. So assuming I need to replace the aux fan control module for my car (N65/1?), where exactly is it for the 1997 E300 Diesel? There's nothing under the driver side headlamp. There's black box sort of behind the headlamp. Is that the one?

Thanks!
