400 E aux fans

[Benz124s]

Hello everyone,

My ' 92 400 E's aux fans aren't working. So far, I've tested the relay and was able to make it click by jumping the brown wires on the dryer switch. The fans won't come on either when I jump the temp sender on the engine. So, I pulled the fan relay and checked for power. I found out that I'm not getting power on terminal 30 for the relay. I've checked fuses 7 and the 15 A fuse near the strut tower. Where does terminal 30 on the relay get its power from? Also, I know my fans and resistor (new) are good since I can jump power to terminals 87 a or b of the relay and the fans turn on.

Thanks in advance,
Dave
