96 C280 Auxilary Fan Issue

I've reviewed the excellent dissussion on auxilary fans that "Vince" initiated a few years back. I do not think my fans are coming; when I looked at the relay panel, I could not find a relay like Vince posted at the end of his thread - none of mine have a fuse attached. Likewise, I could not find the "blue relay" shown in the picture. Is there another location for the auxilarly fan fuse besides the general fuse box, i.e., in the trunk, etc.? I have decent AC so I do not think it's low on refrigerant.
Thanks

1996 & later W202's didn't use relays. They have a fan control module
located behind the left front wheel on the frame rail, under a plactic cover.

The fans are constantly variable in speed, controller will make all variations in speed from signal from A/C controller.
