'00 S320 W220, '98 A160 W168/ sold in 2005 '86 260 E W124 '90 260E W124
Several options therefore (W124)
1st: If you have the regular A/C (non-automatic) it may be a shot blower speed switch
2nd: The resistor assembly for the fan
3rd: Most anoying, the plug (behind the instrument cluster) between the speed switch and the resisitor bank became loose. To check this just unplug the fan,, and apply 12V see if its running. There is a plug just next/behind the fuse box to try this test.
4th: fan is shot, can also be found by the a.m. test.

It was just the Air Blower Fuse
F-15, located outside the main fuse box. It was cheap (1.85 $CD).
When a fuse blows, there must be a reason for that. In this case, I would think the fuse itself (a 30 Am rated flat piece of metal) became weak in the middle part, and eventually cracked. I installed the new one, and everything seems to work fine.
