That depends on which switch you have in the car. Scroll down to #7

W124 Fuse Question

I use a switch from the 201, 006 545 42 24 it is a 100/110 so the aux fan comes on at 100 and the A/C shuts off at 110. I replaced mine last year and it already died. If you have the original switch in your car it is probably not working.
