Hello I have a 95 s420 and my aux fans are not working I changed the cooling fan switch, checked the relays ,and the fuses and changed the aux fan resisters and they still not working I have read that 96 and up w140 have a module on the front frame do 95 and under have a module going to the aux fan resister and where would it be located and has anyone else have this problem and what did you do to fix it

 

Try looking up from under the front bumper, driver's side, right behind the left headlight. If you can see the left side headlamp wiper motor, its right below it! ;-))
